Functions

func Cause

func Cause(err error) error

Cause returns the underlying cause of the error, if possible. An error value has a cause if it implements the following interface:

type causer interface {
       Cause() error
}

If the error does not implement Cause, the original error will be returned. If the error is nil, nil will be returned without further investigation.

func IsGroup

func IsGroup(name string, err error) bool

func IsKind

func IsKind(group, kind string, err error) bool
