How to use the outcome.Outcome function in outcome

raise
            except Exception as e:
                # something bad happened, set exception and exit
                logger.exception("Exception in wait_for predicate!")
                # signal that an error happened
                await p.set(outcome.Error(e))
                raise ListenerExit
            else:
                # exit now if result is true
                if res is True:
                    await p.set(outcome.Value(args))
                    raise ListenerExit

        self.add_temporary_listener(name=event_name, listener=listener)
        try:
            output: outcome.Outcome = await p.wait()
        except Exception:  # cancellations or timeouts
            self.remove_listener_early(event_name, listener=listener)
            raise

        result = output.unwrap()

        # unwrap tuples, if applicable
        if len(result) == 1:
            return result[0]
        return result
