Functions ¶

func OnceFunc ¶

func OnceFunc(f func(ctx context.Context) error) func(ctx context.Context) error

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 Mutex ¶

type Mutex struct {
	sync.Mutex
}

func (*Mutex) WithLock ¶

func (l *Mutex) WithLock(f func())

type Once ¶

type Once[T closer.Closer] struct {
	// contains filtered or unexported fields
}

func OnceValue ¶

func OnceValue[T closer.Closer](f func() T) *Once[T]

func (*Once[T]) Close ¶

func (v *Once[T]) Close(ctx context.Context) (err error)
