type WaitGroup ¶
type WaitGroup struct {
Size int //maximun number of concurrently goroutines
// contains filtered or unexported fields
}
WaitGroup has the same role and close to the same API as the Golang sync.WaitGroup but adds a limit of the amount of goroutines started concurrently.
func New ¶
New creates a WaitGroup. The limit parameter is the maximum amount of goroutines which can be started concurrently.
func (*WaitGroup) Add ¶
func (s *WaitGroup) Add()
Add increments the internal WaitGroup counter. It can be blocking if the limit of spawned goroutines has been reached.
