Can't have multiple Applications on a single server with different state

[fuchsnj]

I don't think this is currently possible, but please correct me if I'm wrong.

HttpServer::new() requires an iterator of Applications (something that implements IntoHttpHandler)

Since the Application has a generic State parameter, if you have applications with a different type for State, you can't create an iterator over these different types.

You have to manually box applications, something like:

HttpServer::new(|| vec![
       Box::new(Application::<State1>::new().finish()),
       Box::new(Application::<State2>::new().finish()),
       Box::new(Application::<State3>::new().finish())])

maybe application should have convenience method.

once you box the application, it doesn't implement actix_web::server::HttpHandler so I don't think this works either

the following trait bounds were not satisfied:
           `std::boxed::Box<actix_web::application::HttpApplication<State1>> : actix_web::server::HttpHandler

you are right! thanks for report

error with app with state and no state. such like

vec![ App::new().resource("/test1", |r| r.f(test1)) .boxed(), App::with_state(AppState::default()) .resource("/test2", |r| r.f(test2)) .boxed(),
