## Our Pledge
We as members, contributors, and leaders pledge to make participation in our
community a harassment-free experience for everyone, regardless of age, body
size, visible or invisible disability, ethnicity, sex characteristics, gender
identity and expression, level of experience, education, socio-economic status,
nationality, personal appearance, race, caste, color, religion, or sexual
identity and orientation.
We pledge to act and interact in ways that contribute to an open, welcoming,
diverse, inclusive, and healthy community.
## Our Standards
Examples of behavior that contributes to a positive environment for our
community include:
* Demonstrating empathy and kindness toward other people
* Being respectful of differing opinions, viewpoints, and experiences
* Giving and gracefully accepting constructive feedback
* Accepting responsibility and apologizing to those affected by our mistakes,
and learning from the experience
* Focusing on what is best not just for us as individuals, but for the overall
community
Examples of unacceptable behavior include:
* The use of sexualized language or imagery, and sexual attention or advances of
any kind
* Trolling, insulting or derogatory comments, and personal or political attacks
* Public or private harassment
* Publishing others' private information, such as a physical or email address,
without their explicit permission
* Other conduct which could reasonably be considered inappropriate in a
professional setting
## Enforcement Responsibilities
Community leaders are responsible for clarifying and enforcing our standards of
acceptable behavior and will take appropriate and fair corrective action in
response to any behavior that they deem inappropriate, threatening, offensive,
or harmful.
Community leaders have the right and responsibility to remove, edit, or reject
comments, commits, code, wiki edits, issues, and other contributions that are
not aligned to this Code of Conduct, and will communicate reasons for moderation
decisions when appropriate.
## Scope
This Code of Conduct applies within all community spaces, and also applies when
an individual is officially representing the community in public spaces.
Examples of representing our community include using an official e-mail address,
posting via an official social media account, or acting as an appointed
representative at an online or offline event.
## Enforcement
Instances of abusive, harassing, or otherwise unacceptable behavior may be
reported to the community leaders responsible for enforcement at
faye.github@gmail.com.
All complaints will be reviewed and investigated promptly and fairly.
All community leaders are obligated to respect the privacy and security of the
reporter of any incident.
## Enforcement Guidelines
Community leaders will follow these Community Impact Guidelines in determining
the consequences for any action they deem in violation of this Code of Conduct:
### 1. Correction
**Community Impact**: Use of inappropriate language or other behavior deemed
unprofessional or unwelcome in the community.

# CBOR Codec in Go
<!-- [![](https://github.com/fxamacker/images/raw/master/cbor/v2.5.0/fxamacker_cbor_banner.png)](#cbor-library-in-go) -->
[fxamacker/cbor](https://github.com/fxamacker/cbor) is a library for encoding and decoding [CBOR](https://www.rfc-editor.org/info/std94) and [CBOR Sequences](https://www.rfc-editor.org/rfc/rfc8742.html).
CBOR is a [trusted alternative](https://www.rfc-editor.org/rfc/rfc8949.html#name-comparison-of-other-binary-) to JSON, MessagePack, Protocol Buffers, etc.&nbsp; CBOR is an Internet&nbsp;Standard defined by [IETF&nbsp;STD&nbsp;94 (RFC&nbsp;8949)](https://www.rfc-editor.org/info/std94) and is designed to be relevant for decades.
`fxamacker/cbor` is used in projects by Arm Ltd., Cisco, EdgeX&nbsp;Foundry, Flow Foundation, Fraunhofer&#8209;AISEC, Kubernetes, Let's&nbsp;Encrypt (ISRG), Linux&nbsp;Foundation, Microsoft, Mozilla, Oasis&nbsp;Protocol, Tailscale, Teleport, [etc](https://github.com/fxamacker/cbor#who-uses-fxamackercbor).
See [Quick&nbsp;Start](#quick-start) and [Releases](https://github.com/fxamacker/cbor/releases/). 🆕 `UnmarshalFirst` and `DiagnoseFirst` can decode CBOR Sequences. `cbor.MarshalToBuffer()` and `UserBufferEncMode` accepts user-specified buffer.

[![Go Report Card](https://goreportcard.com/badge/github.com/fxamacker/cbor)](https://goreportcard.com/report/github.com/fxamacker/cbor)
`fxamacker/cbor` is a CBOR codec in full conformance with [IETF STD&nbsp;94 (RFC&nbsp;8949)](https://www.rfc-editor.org/info/std94). It also supports CBOR Sequences ([RFC&nbsp;8742](https://www.rfc-editor.org/rfc/rfc8742.html)) and Extended Diagnostic Notation ([Appendix G of RFC&nbsp;8610](https://www.rfc-editor.org/rfc/rfc8610.html#appendix-G)).
Features include full support for CBOR tags, [Core Deterministic Encoding](https://www.rfc-editor.org/rfc/rfc8949.html#name-core-deterministic-encoding), duplicate map key detection, etc.
Design balances trade-offs between security, speed, concurrency, encoded data size, usability, etc.
<details><summary>Highlights</summary><p/>
__🚀&nbsp; Speed__
Encoding and decoding is fast without using Go's `unsafe` package. Slower settings are opt-in. Default limits allow very fast and memory efficient rejection of malformed CBOR data.
__🔒&nbsp; Security__
Decoder has configurable limits that defend against malicious inputs. Duplicate map key detection is supported. By contrast, `encoding/gob` is [not designed to be hardened against adversarial inputs](https://pkg.go.dev/encoding/gob#hdr-Security).
Codec passed multiple confidential security assessments in 2022. No vulnerabilities found in subset of codec in a [nonconfidential security assessment](https://github.com/veraison/go-cose/blob/v1.0.0-rc.1/reports/NCC_Microsoft-go-cose-Report_2022-05-26_v1.0.pdf) prepared by NCC&nbsp;Group for Microsoft&nbsp;Corporation.
__🗜&nbsp; Data Size__
Struct tags (`toarray`, `keyasint`, `omitempty`) automatically reduce size of encoded structs. Encoding optionally shrinks float64→32→16 when values fit.
__:jigsaw:&nbsp; Usability__
API is mostly same as `encoding/json` plus interfaces that simplify concurrency for CBOR options. Encoding and decoding modes can be created at startup and reused by any goroutines.
Presets include Core Deterministic Encoding, Preferred Serialization, CTAP2 Canonical CBOR, etc.
__📆&nbsp; Extensibility__
Features include CBOR [extension points](https://www.rfc-editor.org/rfc/rfc8949.html#section-7.1) (e.g. CBOR tags) and extensive settings. API has interfaces that allow users to create custom encoding and decoding without modifying this library.

### Secure Decoding with Configurable Settings
`fxamacker/cbor` has configurable limits, etc. that defend against malicious CBOR data.
By contrast, `encoding/gob` is [not designed to be hardened against adversarial inputs](https://pkg.go.dev/encoding/gob#hdr-Security).

### Smaller Encodings with Struct Tags
Struct tags (`toarray`, `keyasint`, `omitempty`) reduce encoded size of structs.
<details><summary>Example encoding 3-level nested Go struct to 1 byte CBOR</summary><p/>
https://go.dev/play/p/YxwvfPdFQG2
```Go
// Example encoding nested struct (with omitempty tag)
// - encoding/json: 18 byte JSON
// - fxamacker/cbor: 1 byte CBOR
package main
import (
"encoding/hex"
"encoding/json"
"fmt"
"github.com/fxamacker/cbor/v2"
)
type GrandChild struct {
Quux int `json:",omitempty"`
}
type Child struct {
Baz int `json:",omitempty"`
Qux GrandChild `json:",omitempty"`
}
type Parent struct {
Foo Child `json:",omitempty"`
Bar int `json:",omitempty"`
}
func cb() {
results, _ := cbor.Marshal(Parent{})
fmt.Println("hex(CBOR): " + hex.EncodeToString(results))
text, _ := cbor.Diagnose(results) // Diagnostic Notation
fmt.Println("DN: " + text)
}
func js() {
results, _ := json.Marshal(Parent{})
fmt.Println("hex(JSON): " + hex.EncodeToString(results))
text := string(results) // JSON
fmt.Println("JSON: " + text)
}
func main() {
cb()
fmt.Println("-------------")
js()
}
```
Output (DN is Diagnostic Notation):
```
hex(CBOR): a0
DN: {}
-------------
hex(JSON): 7b22466f6f223a7b22517578223a7b7d7d7d

Example using different struct tags together:
![alt text](https://github.com/fxamacker/images/raw/master/cbor/v2.3.0/cbor_struct_tags_api.svg?sanitize=1 "CBOR API and Go Struct Tags")
API is mostly same as `encoding/json`, plus interfaces that simplify concurrency for CBOR options.
## Quick Start
__Install__: `go get github.com/fxamacker/cbor/v2` and `import "github.com/fxamacker/cbor/v2"`.
### Key Points
This library can encode and decode CBOR (RFC 8949) and CBOR Sequences (RFC 8742).
- __CBOR data item__ is a single piece of CBOR data and its structure may contain 0 or more nested data items.
- __CBOR sequence__ is a concatenation of 0 or more encoded CBOR data items.
Configurable limits and options can be used to balance trade-offs.
- Encoding and decoding modes are created from options (settings).
- Modes can be created at startup and reused.
- Modes are safe for concurrent use.
### Default Mode
Package level functions only use this library's default settings.
They provide the "default mode" of encoding and decoding.
```go
// API matches encoding/json for Marshal, Unmarshal, Encode, Decode, etc.
b, err = cbor.Marshal(v) // encode v to []byte b
err = cbor.Unmarshal(b, &v) // decode []byte b to v
decoder = cbor.NewDecoder(r) // create decoder with io.Reader r
err = decoder.Decode(&v) // decode a CBOR data item to v
// v2.7.0 added MarshalToBuffer() and UserBufferEncMode interface.
err = cbor.MarshalToBuffer(v, b) // encode v to b instead of using built-in buf pool.
// v2.5.0 added new functions that return remaining bytes.
// UnmarshalFirst decodes first CBOR data item and returns remaining bytes.
rest, err = cbor.UnmarshalFirst(b, &v) // decode []byte b to v
// DiagnoseFirst translates first CBOR data item to text and returns remaining bytes.
text, rest, err = cbor.DiagnoseFirst(b) // decode []byte b to Diagnostic Notation text
// NOTE: Unmarshal returns ExtraneousDataError if there are remaining bytes,
// but new funcs UnmarshalFirst and DiagnoseFirst do not.
```
__IMPORTANT__: 👉 CBOR settings allow trade-offs between speed, security, encoding size, etc.
- Different CBOR libraries may use different default settings.
- CBOR-based formats or protocols usually require specific settings.
For example, WebAuthn uses "CTAP2 Canonical CBOR" which is available as a preset.
### Presets
Presets can be used as-is or as a starting point for custom settings.
```go
// EncOptions is a struct of encoder settings.
func CoreDetEncOptions() EncOptions // RFC 8949 Core Deterministic Encoding
func PreferredUnsortedEncOptions() EncOptions // RFC 8949 Preferred Serialization
func CanonicalEncOptions() EncOptions // RFC 7049 Canonical CBOR
func CTAP2EncOptions() EncOptions // FIDO2 CTAP2 Canonical CBOR
```
Presets are used to create custom modes.
### Custom Modes
Modes are created from settings. Once created, modes have immutable settings.
💡 Create the mode at startup and reuse it. It is safe for concurrent use.
```Go
// Create encoding mode.
opts := cbor.CoreDetEncOptions() // use preset options as a starting point
opts.Time = cbor.TimeUnix // change any settings if needed
em, err := opts.EncMode() // create an immutable encoding mode
// Reuse the encoding mode. It is safe for concurrent use.
// API matches encoding/json.
b, err := em.Marshal(v) // encode v to []byte b
encoder := em.NewEncoder(w) // create encoder with io.Writer w
err := encoder.Encode(v) // encode v to io.Writer w
```
Default mode and custom modes automatically apply struct tags.
### User Specified Buffer for Encoding (v2.7.0)
`UserBufferEncMode` interface extends `EncMode` interface to add `MarshalToBuffer()`. It accepts a user-specified buffer instead of using built-in buffer pool.
```Go
em, err := myEncOptions.UserBufferEncMode() // create UserBufferEncMode mode
var buf bytes.Buffer
err = em.MarshalToBuffer(v, &buf) // encode v to provided buf
```
### Struct Tags
Struct tags (`toarray`, `keyasint`, `omitempty`) reduce encoded size of structs.

https://go.dev/play/p/YxwvfPdFQG2
```Go

Qux GrandChild `json:",omitempty"`
}
type Parent struct {
Foo Child `json:",omitempty"`
Bar int `json:",omitempty"`
}
func cb() {
results, _ := cbor.Marshal(Parent{})
fmt.Println("hex(CBOR): " + hex.EncodeToString(results))
text, _ := cbor.Diagnose(results) // Diagnostic Notation
fmt.Println("DN: " + text)
}
func js() {
results, _ := json.Marshal(Parent{})
fmt.Println("hex(JSON): " + hex.EncodeToString(results))
text := string(results) // JSON
fmt.Println("JSON: " + text)
}
func main() {
cb()
fmt.Println("-------------")
js()
}
```
Output (DN is Diagnostic Notation):
```
hex(CBOR): a0
DN: {}
-------------
hex(JSON): 7b22466f6f223a7b22517578223a7b7d7d7d

<details><summary>Example using several struct tags</summary><p/>
![alt text](https://github.com/fxamacker/images/raw/master/cbor/v2.3.0/cbor_struct_tags_api.svg?sanitize=1 "CBOR API and Go Struct Tags")
</details>
Struct tags simplify use of CBOR-based protocols that require CBOR arrays or maps with integer keys.
### CBOR Tags
CBOR tags are specified in a `TagSet`.
Custom modes can be created with a `TagSet` to handle CBOR tags.
```go
em, err := opts.EncMode() // no CBOR tags
em, err := opts.EncModeWithTags(ts) // immutable CBOR tags
em, err := opts.EncModeWithSharedTags(ts) // mutable shared CBOR tags
```
`TagSet` and modes using it are safe for concurrent use. Equivalent API is available for `DecMode`.
<details><summary>Example using TagSet and TagOptions</summary><p/>
```go
// Use signedCWT struct defined in "Decoding CWT" example.
// Create TagSet (safe for concurrency).
tags := cbor.NewTagSet()
// Register tag COSE_Sign1 18 with signedCWT type.
tags.Add(
cbor.TagOptions{EncTag: cbor.EncTagRequired, DecTag: cbor.DecTagRequired},
reflect.TypeOf(signedCWT{}),
18)
// Create DecMode with immutable tags.
dm, _ := cbor.DecOptions{}.DecModeWithTags(tags)
// Unmarshal to signedCWT with tag support.
var v signedCWT
if err := dm.Unmarshal(data, &v); err != nil {
return err
}
// Create EncMode with immutable tags.
em, _ := cbor.EncOptions{}.EncModeWithTags(tags)
// Marshal signedCWT with tag number.
if data, err := cbor.Marshal(v); err != nil {
return err
}
```
</details>
### Functions and Interfaces
<details><summary>Functions and interfaces at a glance</summary><p/>
Common functions with same API as `encoding/json`:
- `Marshal`, `Unmarshal`
- `NewEncoder`, `(*Encoder).Encode`
- `NewDecoder`, `(*Decoder).Decode`
NOTE: `Unmarshal` will return `ExtraneousDataError` if there are remaining bytes
because RFC 8949 treats CBOR data item with remaining bytes as malformed.
- 💡 Use `UnmarshalFirst` to decode first CBOR data item and return any remaining bytes.
Other useful functions:
- `Diagnose`, `DiagnoseFirst` produce human-readable [Extended Diagnostic Notation](https://www.rfc-editor.org/rfc/rfc8610.html#appendix-G) from CBOR data.
- `UnmarshalFirst` decodes first CBOR data item and return any remaining bytes.
- `Wellformed` returns true if the the CBOR data item is well-formed.
Interfaces identical or comparable to Go `encoding` packages include:
`Marshaler`, `Unmarshaler`, `BinaryMarshaler`, and `BinaryUnmarshaler`.
The `RawMessage` type can be used to delay CBOR decoding or precompute CBOR encoding.
</details>
### Security Tips
🔒 Use Go's `io.LimitReader` to limit size when decoding very large or indefinite size data.
Default limits may need to be increased for systems handling very large data (e.g. blockchains).
`DecOptions` can be used to modify default limits for `MaxArrayElements`, `MaxMapPairs`, and `MaxNestedLevels`.
## Status
v2.7.0 (June 23, 2024) adds features and improvements that help large projects (e.g. Kubernetes) use CBOR as an alternative to JSON and Protocol Buffers. Other improvements include speedups, improved memory use, bug fixes, new serialization options, etc. It passed fuzz tests (5+ billion executions) and is production quality.
For more details, see [release notes](https://github.com/fxamacker/cbor/releases).
### Prior Release
[v2.6.0](https://github.com/fxamacker/cbor/releases/tag/v2.6.0) (February 2024) adds important new features, optimizations, and bug fixes. It is especially useful to systems that need to convert data between CBOR and JSON. New options and optimizations improve handling of bignum, integers, maps, and strings.
v2.5.0 was released on Sunday, August 13, 2023 with new features and important bug fixes. It is fuzz tested and production quality after extended beta [v2.5.0-beta](https://github.com/fxamacker/cbor/releases/tag/v2.5.0-beta) (Dec 2022) -> [v2.5.0](https://github.com/fxamacker/cbor/releases/tag/v2.5.0) (Aug 2023).
__IMPORTANT__: 👉 Before upgrading from v2.4 or older release, please read the notable changes highlighted in the release notes. v2.5.0 is a large release with bug fixes to error handling for extraneous data in `Unmarshal`, etc. that should be reviewed before upgrading.
See [v2.5.0 release notes](https://github.com/fxamacker/cbor/releases/tag/v2.5.0) for list of new features, improvements, and bug fixes.
See ["Version and API Changes"](https://github.com/fxamacker/cbor#versions-and-api-changes) section for more info about version numbering, etc.

## Who uses fxamacker/cbor
`fxamacker/cbor` is used in projects by Arm Ltd., Berlin Institute of Health at Charité, Chainlink, Cisco, Confidential Computing Consortium, ConsenSys, Dapper&nbsp;Labs, EdgeX&nbsp;Foundry, F5, FIDO Alliance, Fraunhofer&#8209;AISEC, Kubernetes, Let's Encrypt (ISRG), Linux&nbsp;Foundation, Matrix.org, Microsoft, Mozilla, National&nbsp;Cybersecurity&nbsp;Agency&nbsp;of&nbsp;France (govt), Netherlands (govt), Oasis Protocol, Smallstep, Tailscale, Taurus SA, Teleport, TIBCO, and others.
`fxamacker/cbor` passed multiple confidential security assessments. A [nonconfidential security assessment](https://github.com/veraison/go-cose/blob/v1.0.0-rc.1/reports/NCC_Microsoft-go-cose-Report_2022-05-26_v1.0.pdf) (prepared by NCC Group for Microsoft Corporation) includes a subset of fxamacker/cbor v2.4.0 in its scope.
## Standards
`fxamacker/cbor` is a CBOR codec in full conformance with [IETF STD&nbsp;94 (RFC&nbsp;8949)](https://www.rfc-editor.org/info/std94). It also supports CBOR Sequences ([RFC&nbsp;8742](https://www.rfc-editor.org/rfc/rfc8742.html)) and Extended Diagnostic Notation ([Appendix G of RFC&nbsp;8610](https://www.rfc-editor.org/rfc/rfc8610.html#appendix-G)).
Notable CBOR features include:
| CBOR Feature | Description |
| :--- | :--- |
| CBOR tags | API supports built-in and user-defined tags. |
| Preferred serialization | Integers encode to fewest bytes. Optional float64 → float32 → float16. |
| Map key sorting | Unsorted, length-first (Canonical CBOR), and bytewise-lexicographic (CTAP2). |
| Duplicate map keys | Always forbid for encoding and option to allow/forbid for decoding. |
| Indefinite length data | Option to allow/forbid for encoding and decoding. |
| Well-formedness | Always checked and enforced. |
| Basic validity checks | Optionally check UTF-8 validity and duplicate map keys. |
| Security considerations | Prevent integer overflow and resource exhaustion (RFC 8949 Section 10). |
Known limitations are noted in the [Limitations section](#limitations).
Go nil values for slices, maps, pointers, etc. are encoded as CBOR null. Empty slices, maps, etc. are encoded as empty CBOR arrays and maps.
Decoder checks for all required well-formedness errors, including all "subkinds" of syntax errors and too little data.
After well-formedness is verified, basic validity errors are handled as follows:
* Invalid UTF-8 string: Decoder has option to check and return invalid UTF-8 string error. This check is enabled by default.
* Duplicate keys in a map: Decoder has options to ignore or enforce rejection of duplicate map keys.
When decoding well-formed CBOR arrays and maps, decoder saves the first error it encounters and continues with the next item. Options to handle this differently may be added in the future.
By default, decoder treats time values of floating-point NaN and Infinity as if they are CBOR Null or CBOR Undefined.
__Click to expand topic:__
<details>
<summary>Duplicate Map Keys</summary><p>
This library provides options for fast detection and rejection of duplicate map keys based on applying a Go-specific data model to CBOR's extended generic data model in order to determine duplicate vs distinct map keys. Detection relies on whether the CBOR map key would be a duplicate "key" when decoded and applied to the user-provided Go map or struct.
`DupMapKeyQuiet` turns off detection of duplicate map keys. It tries to use a "keep fastest" method by choosing either "keep first" or "keep last" depending on the Go data type.
`DupMapKeyEnforcedAPF` enforces detection and rejection of duplidate map keys. Decoding stops immediately and returns `DupMapKeyError` when the first duplicate key is detected. The error includes the duplicate map key and the index number.
APF suffix means "Allow Partial Fill" so the destination map or struct can contain some decoded values at the time of error. It is the caller's responsibility to respond to the `DupMapKeyError` by discarding the partially filled result if that's required by their protocol.
</details>
<details>
<summary>Tag Validity</summary><p>
This library checks tag validity for built-in tags (currently tag numbers 0, 1, 2, 3, and 55799):
* Inadmissible type for tag content
* Inadmissible value for tag content
Unknown tag data items (not tag number 0, 1, 2, 3, or 55799) are handled in two ways:
* When decoding into an empty interface, unknown tag data item will be decoded into `cbor.Tag` data type, which contains tag number and tag content. The tag content will be decoded into the default Go data type for the CBOR data type.
* When decoding into other Go types, unknown tag data item is decoded into the specified Go type. If Go type is registered with a tag number, the tag number can optionally be verified.
Decoder also has an option to forbid tag data items (treat any tag data item as error) which is specified by protocols such as CTAP2 Canonical CBOR.
For more information, see [decoding options](#decoding-options-1) and [tag options](#tag-options).
</details>
## Limitations
If any of these limitations prevent you from using this library, please open an issue along with a link to your project.
* CBOR `Undefined` (0xf7) value decodes to Go's `nil` value. CBOR `Null` (0xf6) more closely matches Go's `nil`.
* CBOR map keys with data types not supported by Go for map keys are ignored and an error is returned after continuing to decode remaining items.
* When decoding registered CBOR tag data to interface type, decoder creates a pointer to registered Go type matching CBOR tag number. Requiring a pointer for this is a Go limitation.
## Fuzzing and Code Coverage
__Code coverage__ is always 95% or higher (with `go test -cover`) when tagging a release.
__Coverage-guided fuzzing__ must pass billions of execs using before tagging a release. Fuzzing is done using nonpublic code which may eventually get merged into this project. Until then, reports like OpenSSF&nbsp;Scorecard can't detect fuzz tests being used by this project.

## Versions and API Changes
This project uses [Semantic Versioning](https://semver.org), so the API is always backwards compatible unless the major version number changes.
These functions have signatures identical to encoding/json and their API will continue to match `encoding/json` even after major new releases:
`Marshal`, `Unmarshal`, `NewEncoder`, `NewDecoder`, `(*Encoder).Encode`, and `(*Decoder).Decode`.
Exclusions from SemVer:
- Newly added API documented as "subject to change".
- Newly added API in the master branch that has never been tagged in non-beta release.
- If function parameters are unchanged, bug fixes that change behavior (e.g. return error for edge case was missed in prior version). We try to highlight these in the release notes and add extended beta period. E.g. [v2.5.0-beta](https://github.com/fxamacker/cbor/releases/tag/v2.5.0-beta) (Dec 2022) -> [v2.5.0](https://github.com/fxamacker/cbor/releases/tag/v2.5.0) (Aug 2023).
This project avoids breaking changes to behavior of encoding and decoding functions unless required to improve conformance with supported RFCs (e.g. RFC 8949, RFC 8742, etc.) Visible changes that don't improve conformance to standards are typically made available as new opt-in settings or new functions.

## Acknowledgements
Many thanks to all the contributors on this project!
I'm especially grateful to Bastian Müller and Dieter Shirley for suggesting and collaborating on CBOR stream mode, and much more.
I'm very grateful to Stefan Tatschner, Yawning Angel, Jernej Kos, x448, ZenGround0, and Jakob Borg for their contributions or support in the very early days.
Big thanks to Ben Luddy for his contributions in v2.6.0 and v2.7.0.
This library clearly wouldn't be possible without Carsten Bormann authoring CBOR RFCs.
Special thanks to Laurence Lundblade and Jeffrey Yasskin for their help on IETF mailing list or at [7049bis](https://github.com/cbor-wg/CBORbis).
Huge thanks to The Go Authors for creating a fun and practical programming language with batteries included!
This library uses `x448/float16` which used to be included. As a standalone package, `x448/float16` is useful to other projects as well.

Go struct tags (toarray/keyasint/omitempty), Core Deterministic Encoding,
CTAP2, Canonical CBOR, float64->32->16, and duplicate map key detection.
Encoding options allow "preferred serialization" by encoding integers and floats
to their smallest forms (e.g. float16) when values fit.
Struct tags like "keyasint", "toarray" and "omitempty" make CBOR data smaller
and easier to use with structs.
For example, "toarray" tag makes struct fields encode to CBOR array elements. And
"keyasint" makes a field encode to an element of CBOR map with specified int key.

# Basics
The Quick Start guide is at https://github.com/fxamacker/cbor#quick-start
Function signatures identical to encoding/json include:
Marshal, Unmarshal, NewEncoder, NewDecoder, (*Encoder).Encode, (*Decoder).Decode.
Standard interfaces include:
BinaryMarshaler, BinaryUnmarshaler, Marshaler, and Unmarshaler.
Custom encoding and decoding is possible by implementing standard interfaces for
user-defined Go types.
Codec functions are available at package-level (using defaults options) or by
creating modes from options at runtime.
"Mode" in this API means definite way of encoding (EncMode) or decoding (DecMode).
EncMode and DecMode interfaces are created from EncOptions or DecOptions structs.
em, err := cbor.EncOptions{...}.EncMode()
em, err := cbor.CanonicalEncOptions().EncMode()
em, err := cbor.CTAP2EncOptions().EncMode()
Modes use immutable options to avoid side-effects and simplify concurrency. Behavior of
modes won't accidentally change at runtime after they're created.
Modes are intended to be reused and are safe for concurrent use.
EncMode and DecMode Interfaces
// EncMode interface uses immutable options and is safe for concurrent use.
type EncMode interface {
Marshal(v interface{}) ([]byte, error)
NewEncoder(w io.Writer) *Encoder
EncOptions() EncOptions // returns copy of options
}
// DecMode interface uses immutable options and is safe for concurrent use.
type DecMode interface {
Unmarshal(data []byte, v interface{}) error
NewDecoder(r io.Reader) *Decoder
DecOptions() DecOptions // returns copy of options
}
Using Default Encoding Mode
b, err := cbor.Marshal(v)
encoder := cbor.NewEncoder(w)
err = encoder.Encode(v)
Using Default Decoding Mode
err := cbor.Unmarshal(b, &v)
decoder := cbor.NewDecoder(r)
err = decoder.Decode(&v)
Creating and Using Encoding Modes
// Create EncOptions using either struct literal or a function.
opts := cbor.CanonicalEncOptions()
// If needed, modify encoding options
opts.Time = cbor.TimeUnix
// Create reusable EncMode interface with immutable options, safe for concurrent use.
em, err := opts.EncMode()
// Use EncMode like encoding/json, with same function signatures.
b, err := em.Marshal(v)
// or
encoder := em.NewEncoder(w)
err := encoder.Encode(v)
// NOTE: Both em.Marshal(v) and encoder.Encode(v) use encoding options
// specified during creation of em (encoding mode).
# CBOR Options
Predefined Encoding Options: https://github.com/fxamacker/cbor#predefined-encoding-options
Encoding Options: https://github.com/fxamacker/cbor#encoding-options
Decoding Options: https://github.com/fxamacker/cbor#decoding-options
# Struct Tags
Struct tags like `cbor:"name,omitempty"` and `json:"name,omitempty"` work as expected.
If both struct tags are specified then `cbor` is used.
Struct tags like "keyasint", "toarray", and "omitempty" make it easy to use
very compact formats like COSE and CWT (CBOR Web Tokens) with structs.
For example, "toarray" makes struct fields encode to array elements. And "keyasint"
makes struct fields encode to elements of CBOR map with int keys.

Struct tags are listed at https://github.com/fxamacker/cbor#struct-tags-1
# Tests and Fuzzing
Over 375 tests are included in this package. Cover-guided fuzzing is handled by
a private fuzzer that replaced fxamacker/cbor-fuzz years ago.

[![Release](https://img.shields.io/github/release/x448/float16.svg?style=flat-square)](https://github.com/x448/float16/releases)
[![License](http://img.shields.io/badge/license-mit-blue.svg?style=flat-square)](https://raw.githubusercontent.com/x448/float16/master/LICENSE)
`float16` package provides [IEEE 754 half-precision floating-point format (binary16)](https://en.wikipedia.org/wiki/Half-precision_floating-point_format) with IEEE 754 default rounding for conversions. IEEE 754-2008 refers to this 16-bit floating-point format as binary16.
IEEE 754 default rounding ("Round-to-Nearest RoundTiesToEven") is considered the most accurate and statistically unbiased estimate of the true result.
All possible 4+ billion floating-point conversions with this library are verified to be correct.
Lowercase "float16" refers to IEEE 754 binary16. And capitalized "Float16" refers to exported Go data type provided by this library.
## Features
Current features include:
* float16 to float32 conversions use lossless conversion.
* float32 to float16 conversions use IEEE 754-2008 "Round-to-Nearest RoundTiesToEven".
* conversions using pure Go take about 2.65 ns/op on a desktop amd64.
* unit tests provide 100% code coverage and check all possible 4+ billion conversions.
* other functions include: IsInf(), IsNaN(), IsNormal(), PrecisionFromfloat32(), String(), etc.
* all functions in this library use zero allocs except String().
## Status
This library is used by [fxamacker/cbor](https://github.com/fxamacker/cbor) and is ready for production use on supported platforms. The version number < 1.0 indicates more functions and options are planned but not yet published.
Current status:
* core API is done and breaking API changes are unlikely.
* 100% of unit tests pass:
* short mode (`go test -short`) tests around 65765 conversions in 0.005s.
* normal mode (`go test`) tests all possible 4+ billion conversions in about 95s.
* 100% code coverage with both short mode and normal mode.
* tested on amd64 but it should work on all little-endian platforms supported by Go.
Roadmap:
* add functions for fast batch conversions leveraging SIMD when supported by hardware.
* speed up unit test when verifying all possible 4+ billion conversions.

Conversions from float16 to float32 are lossless conversions. All 65536 possible float16 to float32 conversions (in pure Go) are confirmed to be correct.
Unit tests take a fraction of a second to check all 65536 expected values for float16 to float32 conversions.
## Float32 to Float16 Conversion
Conversions from float32 to float16 use IEEE 754 default rounding ("Round-to-Nearest RoundTiesToEven"). All 4294967296 possible float32 to float16 conversions (in pure Go) are confirmed to be correct.
Unit tests in normal mode take about 1-2 minutes to check all 4+ billion float32 input values and results for Fromfloat32(), FromNaN32ps(), and PrecisionFromfloat32().
Unit tests in short mode use a small subset (around 229 float32 inputs) and finish in under 0.01 second while still reaching 100% code coverage.
## Usage
Install with `go get github.com/x448/float16`.
```
// Convert float32 to float16
pi := float32(math.Pi)
pi16 := float16.Fromfloat32(pi)
// Convert float16 to float32
pi32 := pi16.Float32()
// PrecisionFromfloat32() is faster than the overhead of calling a function.
// This example only converts if there's no data loss and input is not a subnormal.
if float16.PrecisionFromfloat32(pi) == float16.PrecisionExact {
pi16 := float16.Fromfloat32(pi)
}
```
## Float16 Type and API
Float16 (capitalized) is a Go type with uint16 as the underlying state. There are 6 exported functions and 9 exported methods.
```
package float16 // import "github.com/x448/float16"
// Exported types and consts
type Float16 uint16
const ErrInvalidNaNValue = float16Error("float16: invalid NaN value, expected IEEE 754 NaN")
// Exported functions
Fromfloat32(f32 float32) Float16 // Float16 number converted from f32 using IEEE 754 default rounding
with identical results to AMD and Intel F16C hardware. NaN inputs
are converted with quiet bit always set on, to be like F16C.
FromNaN32ps(nan float32) (Float16, error) // Float16 NaN without modifying quiet bit.
// The "ps" suffix means "preserve signaling".
// Returns sNaN and ErrInvalidNaNValue if nan isn't a NaN.
Frombits(b16 uint16) Float16 // Float16 number corresponding to b16 (IEEE 754 binary16 rep.)
NaN() Float16 // Float16 of IEEE 754 binary16 not-a-number
Inf(sign int) Float16 // Float16 of IEEE 754 binary16 infinity according to sign
PrecisionFromfloat32(f32 float32) Precision // quickly indicates exact, ..., overflow, underflow
// (inline and < 1 ns/op)
// Exported methods
(f Float16) Float32() float32 // float32 number converted from f16 using lossless conversion
(f Float16) Bits() uint16 // the IEEE 754 binary16 representation of f
(f Float16) IsNaN() bool // true if f is not-a-number (NaN)
(f Float16) IsQuietNaN() bool // true if f is a quiet not-a-number (NaN)
(f Float16) IsInf(sign int) bool // true if f is infinite based on sign (-1=NegInf, 0=any, 1=PosInf)
(f Float16) IsFinite() bool // true if f is not infinite or NaN
(f Float16) IsNormal() bool // true if f is not zero, infinite, subnormal, or NaN.
(f Float16) Signbit() bool // true if f is negative or negative zero
(f Float16) String() string // string representation of f to satisfy fmt.Stringer interface
```
See [API](https://godoc.org/github.com/x448/float16) at godoc.org for more info.
## Benchmarks
Conversions (in pure Go) are around 2.65 ns/op for float16 -> float32 and float32 -> float16 on amd64. Speeds can vary depending on input value.
```
All functions have zero allocations except float16.String().
FromFloat32pi-2 2.59ns ± 0% // speed using Fromfloat32() to convert a float32 of math.Pi to Float16
ToFloat32pi-2 2.69ns ± 0% // speed using Float32() to convert a float16 of math.Pi to float32
Frombits-2 0.29ns ± 5% // speed using Frombits() to cast a uint16 to Float16
PrecisionFromFloat32-2 0.29ns ± 1% // speed using PrecisionFromfloat32() to check for overflows, etc.
```
## System Requirements
* Tested on Go 1.11, 1.12, and 1.13 but it should also work with older versions.
* Tested on amd64 but it should also work on all little-endian platforms supported by Go.
