}

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.

Backup(Error)

Backing up a room key has failed.

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.

Implementations

impl CryptoStoreError

pub fn backend<E>(error: E) -> Self

where E: Error + Send + Sync + 'static,

Create a new Backend error.

Shorthand for StoreError::Backend(Box::new(error)).

Trait Implementations

impl Debug for CryptoStoreError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for CryptoStoreError

fn fmt(&self, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for CryptoStoreError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.
