Function IsUnsupported

error.go:33–38

IsUnsupported returns true if err is the result of trying an unsupported operation. It is equivalent to finding the first error in err's chain that implements type unsupported interface { Unsupported() bool } and then calling the Unsupported() method.

(err error)

//
// and then calling the Unsupported() method.
func IsUnsupported(err error) bool {
	var u interface {
		Unsupported() bool
	}
	return errors.As(err, &u) && u.Unsupported()
}
