Enum SessionBackend 

pub enum SessionBackend {
    Database(AnySessionStore),
    File(FileSessionStore),
}

Wraps whichever of AnySessionStore/FileSessionStore Config:: session_driver selected, so session_layer always returns the same concrete SessionManagerLayer<SessionBackend> type regardless of which one is active - tower_sessions::SessionManagerLayer<S> is generic over one concrete S, so the alternative to an enum here would be trait- object erasure (Arc<dyn SessionStore>), more machinery for no real benefit over a two-variant match in each trait method.

Variants

Database(AnySessionStore)

File(FileSessionStore)
