Trait gotham::middleware::session::Backend [−] [src]

pub trait Backend: Send {
    fn persist_session(
        &self, 
        identifier: SessionIdentifier, 
        content: &[u8]
    ) -> Result<(), SessionError>;

    fn read_session(
        &self, 
        identifier: SessionIdentifier
    ) -> Box<Future<Item = Option<Vec<u8>>, Error = SessionError> + Send>;

    fn drop_session(
        &self, 
        identifier: SessionIdentifier
    ) -> Result<(), SessionError>;
}

A Backend receives session data and stores it, and recalls the session data subsequently.

All session data is serialized into a Vec<u8> which is treated as opaque by the backend. The serialization format is subject to change and must not be relied upon by the Backend.

Required Methods

Persists a session, either creating a new session or updating an existing session.

Retrieves a session from the underlying storage.

The returned future will resolve to an Option<Vec<u8>> on success, where a value of None indicates that the session is not available for use and a new session should be established.

Drops a session from the underlying storage.
