Function WrapPrefix

error.go:123–140

WrapPrefix makes an Error from the given value. If that value is already an error then it will be used directly, if not, it will be passed to fmt.Errorf("%v"). The prefix parameter is used to add a prefix to the error message when calling Error(). The skip parameter indicates how far up the stack to

(e interface{}, prefix string, skip int)

// up the stack to start the stacktrace. 0 is from the current call,
// 1 from its caller, etc.
func WrapPrefix(e interface{}, prefix string, skip int) *Error {
	if e == nil {
		return nil
	}

	err := Wrap(e, 1+skip)

	if err.prefix != "" {
		prefix = fmt.Sprintf("%s: %s", prefix, err.prefix)
	}

	return &Error{
		Err:    err.Err,
		stack:  err.stack,
		prefix: prefix,
	}

}

// Errorf creates a new error with the given message. You can use it
// as a drop-in replacement for fmt.Errorf() to provide descriptive
