func (*Manager) Fire

func (m *Manager) Fire(event Event)

Fire fires an event and returns after all subscribers are complete handling it. Any panic by a subscriber is caught so firing the event to the next subscriber can proceed .

func (m *Manager) FireParallel(event Event, after ...HandlerFn)

func (*Manager) Wait

func (m *Manager) Wait()
