}

An error observed in the EventCache.

Variants

NotSubscribedYet

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

RoomNotFound

Room is not found.

Fields

room_id: OwnedRoomId

The ID of the room not being found.

BackpaginationError(Box<Error>)

An error has been observed while back-paginating.

AlreadyBackpaginating

Back-pagination was already happening in a given room, where we tried to back-paginate again.

Storage(EventCacheStoreError)

An error happening when interacting with storage.

LockingStorage(LockStoreError)

An error happening when attempting to (cross-process) lock storage.

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.

LinkedChunkLoader(LazyLoaderError)

An error happening when interacting with the LinkedChunk’s lazy loader.

InvalidLinkedChunkMetadata

An error happened when reading the metadata of a linked chunk, upon reload.

Fields

details: String

A string containing details about the error.

Trait Implementations
