Expand description

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.
