Extension methods for Storage to help read events from MirroredStorage.

Required Methods

fn modify( &mut self, entity: Entity, ) -> Option<(&mut C, &mut EventChannel<C::Event>)>

Get a mutable reference to the component and the event channel for update events.

fn event_channel(&mut self) -> &mut EventChannel<C::Event>

Get a mutable reference to the event channel for update events.

Provided Methods

fn register_reader(&mut self) -> ReaderId<C::Event>

Register a new reader of insertion and removal events.
