Expand description

The crypto store’s error type.

Variants§

§

AccountUnset

The account that owns the sessions, group sessions, and devices wasn’t found.

§

MismatchedAccount

The store doesn’t support multiple accounts and data from another device was discovered.

Fields

§expected: (OwnedUserId, OwnedDeviceId)

The expected user/device id pair.

§got: (OwnedUserId, OwnedDeviceId)

The user/device id pair that was loaded from the store.

§

Io(Error)

An IO error occurred.

§

UnpicklingError

Failed to decrypt an pickled object.

§

Pickle(PickleError)

Failed to decrypt an pickled object.

§

SessionCreation(SessionCreationError)

The received room key couldn’t be converted into a valid Megolm session.

§

IdentifierValidation(IdParseError)

A Matrix identifier failed to be validated.

§

Serialization(Error)

The store failed to (de)serialize a data type.

§

UnsupportedDatabaseVersion(usize, usize)

The database format has changed in a backwards incompatible way.

§

Backend(Box<dyn Error + Send + Sync>)

A problem with the underlying database backend

§

InvalidLockGeneration(String)

An error due to an invalid generation in a cross-process locking scheme.
