The interface to retrieve and save the current session data from/to the chosen storage backend.

You can provide your own custom session store backend by implementing this trait.

Required Methods

fn load( &self, session_key: &SessionKey ) -> impl Future<Output = Result<Option<HashMap<String, String>>, LoadError>>

Loads the session state associated to a session key.

fn save( &self, session_state: HashMap<String, String>, ttl: &Duration ) -> impl Future<Output = Result<SessionKey, SaveError>>

Persist the session state for a newly created session.

Returns the corresponding session key.

fn update( &self, session_key: SessionKey, session_state: HashMap<String, String>, ttl: &Duration ) -> impl Future<Output = Result<SessionKey, UpdateError>>

Updates the session state associated to a pre-existing session key.

fn update_ttl( &self, session_key: &SessionKey, ttl: &Duration ) -> impl Future<Output = Result<(), Error>>

Updates the TTL of the session state associated to a pre-existing session key.

fn delete( &self, session_key: &SessionKey ) -> impl Future<Output = Result<(), Error>>

Deletes a session from the store.
