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

Notifier allows waiting until Notify is called (or context is cancelled). Each Notify unblocks one Wait. Safe for concurrent use.

func New() *Notifier

New returns a new Notifier.

func (n *Notifier) Notify()

Notify unblocks one waiter. Non-blocking; if no one is waiting, the next Wait will return immediately.

func (n *Notifier) Wait(ctx context.Context) error

Wait blocks until Notify is called or ctx is cancelled. Returns nil if Notify was called, otherwise ctx.Err().
