Trait actix_web_flash_messages::storage::FlashMessageStore

pub trait FlashMessageStore: Send + Sync {
    fn load(
        &self, 
        request: &HttpRequest
    ) -> Result<Vec<FlashMessage>, LoadError>;
    fn store(
        &self, 
        messages: &[FlashMessage], 
        request: HttpRequest, 
        response: &mut ResponseHead
    ) -> Result<(), StoreError>;
}

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.
