Struct EventCache 

pub struct EventCache { /* private fields */ }

An event cache, providing lots of useful functionality for clients.

Cloning is shallow, and thus is cheap to do.

See also the module-level comment.

Implementations

impl EventCache

pub fn subscribe(&self) -> Result<()>

Starts subscribing the EventCache to sync responses, if not done before.

Re-running this has no effect if we already subscribed before, and is cheap.

pub async fn clear_all_rooms(&self) -> Result<()>

Cleanly clear all the rooms’ event caches.

This will notify any live observers that the room has been cleared.

pub fn subscribe_to_room_generic_updates( &self, ) -> Receiver<RoomEventCacheGenericUpdate>

Subscribe to room generic updates.

If one wants to listen what has changed in a specific room, the RoomEventCache::subscribe is recommended. However, the RoomEventCacheSubscriber type triggers side-effects.

If one wants to get a high-overview, generic, updates for rooms, and without side-effects, this method is recommended. For example, it doesn’t provide a list of new events, but rather a RoomEventCacheGenericUpdate::UpdateTimeline update. Also, dropping the receiver of this channel will not trigger any side-effect.
