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)

}

```
