Types

type EventBroadcast

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

EventBroadcast is implementation of broadcast notify about event Zero value is usable, must not copy after first call any method

func (*EventBroadcast) Broadcast

func (b *EventBroadcast) Broadcast()

func (*EventBroadcast) Waiter

func (b *EventBroadcast) Waiter() OneTimeWaiter

Waiter return channel, that will close when next event will be broadcast. For prevent race between subscribe and event client code must subscribe at first, then check condition if false - wait closing channed and check condition again

type LastUsage

type LastUsage interface {
	Get() time.Time
	Start() (stop func())
}

	// contains filtered or unexported fields
}

func (*OneTimeWaiter) Done

func (w *OneTimeWaiter) Done() <-chan struct{}

type RWMutex

type RWMutex struct {
	sync.RWMutex
}

func (*RWMutex) WithLock
