Share the same app-state between rest and websocket endpoints?

[fweichselbaum]

I am trying to create a backend for a simple turn-based game, and the functionality to create a game works fine. The games are managed in by the HttpServer App via the app_data method.

let games: Arc<Mutex<Vec<Game>>> = GameList::default();

HttpServer::new(move || {
    App::new()
        .app_data(Data::new(games.clone()))
        ...
})
...

Then I access the state in the REST endpoints via the actix_web::web::Data struct:

#[post("/games/new")]
pub async fn new_game(games: web::Data<GameList>) -> impl Responder {
    ...

I plan on handling the actual game implementation with websockets, but by now I haven't found a method to do access the existing app state created with the REST endpoints.

Since I am fairly new to actix and rust in general, my question now is if it is even possible and if yes, how?
