Expand description

State store specific error type.

Variants

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

An error happened in the underlying database backend.

`Json(Error)`

An error happened while serializing or deserializing some data.

`Identifier(IdParseError)`

An error happened while deserializing a Matrix identifier, e.g. an user id.

`StoreLocked`

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

`UnencryptedStore`

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

`Encryption(String)`

The store failed to encrypt or decrypt some data.

`Codec(String)`

The store failed to encode or decode some data.

`UnsupportedDatabaseVersion(usize, usize)`

The database format has changed in a backwards incompatible way.

`Redaction(Error)`

Redacting an event in the store has failed.

This should never happen.

Implementations

impl StoreError

pub fn backend<E>(error: E) -> Self where
E: Error + Send + Sync + 'static,
