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(Error)

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 + Sync + Send>)

A problem with the underlying database backend

InvalidLockGeneration(String)

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