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`.
### Usage
```go
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)
}
```
You can also limit the number of asynchronous tasks
```go
runner := async.NewRunner(tasks...).WithLimit(3)
if err := runner.Run(ctx); err != nil {
log.Error(e)
}
```
