type WrapErr ¶

type WrapErr struct {
	Err  error
	Wrap error
}

WrapErr wraps an underlying error with another error

Example usage:

var ErrLimit = errors.New("Limit reached")
...
func someFunc() error {
  return wrapper.WrapErr{Err: fmt.Errorf("Limit %d reached on %s", limit, instance), Wrap: ErrLimit}
}
...
if errors.Is(err, ErrLimit) { ... }

This makes it easier to include a custom error message while also allowing

func New(err, wrap error) WrapErr

func (e WrapErr) Error() string

func (e WrapErr) Unwrap() error
