Provides a safe way to execute functions asynchronously, recovering them in case of panic. It also provides an error stack aiming to facilitate fail causes discovery, and a simple way to control execution flow without WaitGroup.

var ( user User songs []Songs photos []Photos )

err := async.Run(ctx, func(ctx context.Context) error { user, err = user.Get(ctx, id) return err }, func(ctx context.Context) error { songs, err = song.GetByUserID(ctx, id) return err }, func(ctx context.Context) error { photos, err = photo.GetByUserID(ctx, id) return err }, )

if err != nil { log.Error(err) }

runner := async.NewRunner(tasks...).WithLimit(3) if err := runner.Run(ctx); err != nil { log.Error(e) }
