Enum matrix_sdk_base::event_cache::store::EventCacheStoreError

pub enum EventCacheStoreError {
    Backend(Box<dyn Error + Send + Sync>),
    Locked,
    Unencrypted,
    Encryption(StoreEncryptionError),
    Codec(Utf8Error),
    UnsupportedDatabaseVersion(usize, usize),
}

Event cache store specific error type.

Variants

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

An error happened in the underlying database backend.

Locked

The store is locked with a passphrase and an incorrect passphrase was given.

Unencrypted

An unencrypted store was tried to be unlocked with a passphrase.

Encryption(StoreEncryptionError)

The store failed to encrypt or decrypt some data.

Codec(Utf8Error)

The store failed to encode or decode some data.

UnsupportedDatabaseVersion(usize, usize)

The database format has changed in a backwards incompatible way.

Implementations

impl EventCacheStoreError

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

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

Create a new Backend error.

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

Trait Implementations

impl Debug for EventCacheStoreError

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

Formats the value using the given formatter.

impl Display for EventCacheStoreError

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

Formats the value using the given formatter.

impl Error for EventCacheStoreError

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

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.

impl From<Error> for EventCacheStoreError

fn from(source: StoreEncryptionError) -> Self

Converts to this type from the input type.

impl From<Utf8Error> for EventCacheStoreError

fn from(source: Utf8Error) -> Self

Converts to this type from the input type.
