Types

type Interface

type Interface interface {
	// Done returns a chan that blocks until Close is called. It never returns data.
	Done() <-chan struct{}
	// Close closes the latch; all future calls to Closed return true. Safe to invoke multiple times.
	Close()
	// Closed returns false while the latch is "open" and true after it has been closed via Close.
	Closed() bool
}
