// As is a variant of errors.As() that leverages generics to present a nicer interface.
//
// //this code:
// var perr os.PathError
// if errors.As(err, &perr) {
// handle(perr)
// }
// //can be rewritten as:
// if perr, ok := errext.As[os.PathError](err); ok {
// handle(perr)
// }
//
// This is sometimes more verbose (like in this example), but allows to scope
// the specific error variable to the condition's then-branch, and also looks
// more idiomatic to developers already familiar with type casts.
func As[T error](err error) (T, bool) {
var result T
ok := errors.As(err, &result)
return result, ok
