}Expand description
The interface to retrieve and dispatch flash messages.
actix-web-flash-messages provides two implementation of flash messages:
- a cookie-based one,
CookieMessageStore, using a signed cookie to store and retrieve messages; - a session-based one,
SessionMessageStore, which attaches flash messages to the current session.
You can provide your own custom message store backend by implementing this trait.
