Types

type Group

type Group struct {
	// contains filtered or unexported fields
}

Group manages a set of goroutines with related lifetimes.

func (*Group) Add

func (g *Group) Add(fn func(<-chan struct{}))

Add adds a function to the Group. The function will be exectuted in its own goroutine when Run is called. Add must be called before Run.

func (*Group) Run

func (g *Group) Run()

Run exectues each function registered with Add in its own goroutine. Run blocks until each function has returned. The first function to return will trigger the closure of the channel passed to each function, who should in turn, return.
