- Passes through most
golang.org/x/xerrorsfunctions and interfaces to make life easier. - A complete drop-in replacement for
xerrors - A complete drop-in replacement for
errgroup ErrorListhandles multiple errors in a sane way.ErrorListcan optionally be toggled to enable thread safety.Try/Catchneeds doc.- All errors can support be toggled to support JSON output.
oerrs was made to make error handling easier
var errs oerrs.ErrorList
errs.PushIf(step1())
errs.PushIf(step2())
if errs.PushIf(step3()) {
// do something
}
return errs.Err()oerrs.ErrorList implements error
if err := something(); err != nil {
if el, ok := err.(*oerrs.ErrorList); ok {
// Use merr.Errors
}
// or
var el *oerrs.ErrorList
if errors.As(err, &el) {
// use el.Errors
}
}
// try / catch
func doStuff() (res Response, err error) {
defer oerrs.Catch(&err, nil)
a := Try1(someFunThatReturnValAndErr())
// do something with a
b := Try1(someOtherFunc(a))
return a + b, nil
