Constants

const (
	// KindNewEventPersisted is a hook which is called with *types.HeaderedEvent
	// It is run when a new event is persisted in the roomserver.
	// Usage:
	//   hooks.Attach(hooks.KindNewEventPersisted, func(headeredEvent interface{}) { ... })
	KindNewEventPersisted = "new_event_persisted"
	// KindNewEventReceived is a hook which is called with *types.HeaderedEvent
	// It is run before a new event is processed by the roomserver. This hook can be used
	// to modify the event before it is persisted by adding data to `unsigned`.
	// Usage:
	//   hooks.Attach(hooks.KindNewEventReceived, func(headeredEvent interface{}) {
	//     ev := headeredEvent.(*types.HeaderedEvent)
	//     _ = ev.SetUnsignedField("key", "val")
	//   })
	KindNewEventReceived = "new_event_received"
