Struct gotham::middleware::session::SessionData[−][src]

pub struct SessionData<T> where
    T: Default + Serialize + for<'de> Deserialize<'de> + Send + 'static,  { /* fields omitted */ }
Expand description

The wrapping type for application session data.

The application will receive a SessionData<T> via the State container, where T is the session type given to NewSessionMiddleware.

Examples

#[derive(Default, Deserialize, Serialize)]
struct MySessionType {
    items: Vec<String>,
}

fn my_handler(state: State) -> (State, Response<Body>) {
    // The `Router` has a `NewSessionMiddleware<_, MySessionType>` in a pipeline which is
    // active for this handler.
    let body = {
        let session = SessionData::<MySessionType>::borrow_from(&state);
        format!("{:?}", session.items)
    };

    let response = create_response(&state,
                                   StatusCode::OK,
                                   mime::TEXT_PLAIN,
                                   body);

    (state, response)
}
