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 enable_storage(&self) -> Result<()>

Enable storing updates to storage, and reload events from storage.

Has an effect only the first time it’s called. It’s safe to call it multiple times.

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 event(&self, event_id: &EventId) -> Option<SyncTimelineEvent>

Try to find an event by its ID in all the rooms.

pub async fn add_initial_events( &self, room_id: &RoomId, events: Vec<SyncTimelineEvent>, prev_batch: Option<String>, ) -> Result<()>

Add an initial set of events to the event cache, reloaded from a cache.

TODO: temporary for API compat, as the event cache should take care of its own store.
