Enum EventCacheError

pub enum EventCacheError {
    NotSubscribedYet,
    RoomNotFound(OwnedRoomId),
    UnknownBackpaginationToken,
    BackpaginationError(PaginatorError),
    ClientDropped,
}

An error observed in the EventCache.

Variants

NotSubscribedYet

The EventCache instance hasn’t been initialized with EventCache::subscribe

RoomNotFound(OwnedRoomId)

The room hasn’t been found in the client.

Technically, it’s possible to request a RoomEventCache for a room that is not known to the client, leading to this error.

UnknownBackpaginationToken

The given back-pagination token is unknown to the event cache.

BackpaginationError(PaginatorError)

An error has been observed while back-paginating.

ClientDropped

The EventCache owns a weak reference to the Client it pertains to. It’s possible this weak reference points to nothing anymore, at times where we try to use the client.
