Actix websockets with an AppState

I am trying to combine the Actix examples for Diesel and WebSockets. After adding the WebSockets one, it does not have the AppState in place.



I cannot get this to work, even after looking and comparing to other code (there have been version differences, but after fixing them the result was the same error).



Here is my last (failing) commit, describing everything I got. The repo can be checked out and run.



$ rustup default nightly
$ cargo check
Checking rust-diesel v0.1.0 (~/pansen/rust_diesel)
error[E0271]: type mismatch resolving `<handlers::ws::MyWebSocket as actix::Actor>::Context == actix_web::ws::WebsocketContext<handlers::ws::MyWebSocket, AppState>`
--> src/main.rs:63:51
|
63 | r.method(http::Method::GET).f(|r| ws::start(r, handlers::ws::MyWebSocket::new())),
| ^^^^^^^^^ expected (), found struct `AppState`
|
= note: expected type `actix_web::ws::WebsocketContext<_, ()>`
found type `actix_web::ws::WebsocketContext<_, AppState>`
= note: required by `actix_web::ws::start`

You need the State extractor. Then store State<AppState> in your WebSocket actor.
