Function asFiberError

app.go:644–655

asFiberError reports whether err is or wraps a *Error and returns it. A direct *Error is matched alloc-free by a type assertion; wrapped or joined errors fall back to errors.As.

(err error)

// *Error is matched alloc-free by a type assertion; wrapped or joined errors
// fall back to errors.As.
func asFiberError(err error) (*Error, bool) {
	if err == nil {
		return nil, false
	}
	if e, ok := err.(*Error); ok { //nolint:errorlint // intentional fast path; wrapped/joined errors fall through to errors.As below
		return e, true
	}
	// Declared here so errors.As's &target escapes only on this slow path.
	var target *Error
	matched := errors.As(err, &target)
	return target, matched
