|
|
// The registry is used by the Details() function. Registered error properties will
|
|
// be included in Details() output, if the value of that error property is not nil.
|
|
// For example:
|
|
//
|
|
// err := New("boom")
|
|
// err = err.WithValue(colorKey, "red")
|
|
// fmt.Println(Details(err))

// // Output:
|
|
// // boom
|
|
// //
|
|
// // <stacktrace>
|
|
//
|
|
// RegisterDetail("Color", colorKey)
|
|
// fmt.Println(Details(err))

// In other words, it's up to the author of the package which generates the errors
|
|
// to publish printable error details, not the callers of the package.
