Types

type Waker

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

Waker is used to wake up a sleeper when some event occurs. It debounces multiple wakeup calls occurring between each sleep, and wakeups are non-blocking to avoid having to coordinate goroutines.

func NewWaker

func NewWaker() *Waker

NewWaker creates a new Waker.

func (*Waker) Sleep

func (w *Waker) Sleep() <-chan struct{}

Sleep returns a channel that blocks until Wake() is called.

func (*Waker) Wake

func (w *Waker) Wake()

Wake wakes up the sleeper.
