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
}

Interface funcs are safe to invoke concurrently.

func New ¶

func New() Interface

New returns a new "open" latch such that Closed returns false until Close is invoked.

type L ¶

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

func (*L) Close ¶

func (l *L) Close()

Close may panic for an uninitialized L

func (*L) Closed ¶

func (l *L) Closed() (result bool)

func (*L) Done ¶

func (l *L) Done() <-chan struct{}

func (*L) Reset ¶

func (l *L) Reset() *L

Reset clears the state of the latch, not safe to execute concurrently with other L methods.
