Snap.Snaplet.Session.SessionManager
Description
This module is meant to be used mainly by Session backend developers, who would naturally need access to ISessionManager class internals. You can also use it if you need low-level access to the backend functionality.
- data SessionManager = forall a . ISessionManager a => SessionManager a
- class ISessionManager r where
Documentation
data SessionManager Source
Any Haskell record that is a member of the ISessionManager
typeclass can be stuffed inside a SessionManager to enable all
session-related functionality.
To use sessions in your application, just find a Backend that would
produce one for you inside of your Initializer. See
initCookieSessionManager in
CookieSession for a built-in option
that would get you started.
