matrix_sdk::event_cache

Struct RoomEventCache

Source
pub struct RoomEventCache { /* private fields */ }
Expand description

A subset of an event cache, for a room.

Cloning is shallow, and thus is cheap to do.

Implementations§

Source§

impl RoomEventCache

Source

pub async fn subscribe( &self, ) -> Result<(Vec<SyncTimelineEvent>, Receiver<RoomEventCacheUpdate>)>

Subscribe to room updates for this room, after getting the initial list of events. XXX: Could/should it use some kind of Observable instead? Or not something async, like explicit handlers as our event handlers?

Source

pub fn pagination(&self) -> RoomPagination

Return a RoomPagination API object useful for running back-pagination queries in the current room.

Source

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

Try to find an event by id in this room.

Source

pub async fn event_with_relations( &self, event_id: &EventId, filter: Option<Vec<RelationType>>, ) -> Option<(SyncTimelineEvent, Vec<SyncTimelineEvent>)>

Try to find an event by id in this room, along with its related events.

You can filter which types of related events to retrieve using filter. None will retrieve related events of any type.

Source

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

Clear all the storage for this RoomEventCache.

This will get rid of all the events from the linked chunk and persisted storage.

Source

pub async fn debug_string(&self) -> Vec<String>

Return a nice debug string (a vector of lines) for the linked chunk of events for this room.
