actix_service::AppRouting should be public

[Necoo33]

Hello, i'm trying to implement an authentication flow, in that moment i'm coding a cookie refresh middleware in v4.9 and with using actix_web::app::App::wrap function i encountered an issue. Because of that actix_web::actix_service::AppRouting is not public i cannot put it inside a wrapper function, which that makes my code messier. my wrap function remained like this:

// other services
            .wrap_fn(move |req, srv| {
                let auth_cookie_name = match env::var("AUTH_COOKIE_NAME") {
                    Ok(name) => name,
                    Err(_) => "auth_cookie".to_string()
                };

                let cookie = req.cookie(&auth_cookie_name);

                let fut = srv.call(req);
            
                async move {
                    let mut res = fut.await?;
            
                    res = utils::refresh_cookies(cookie, auth_cookie_name, res).await.unwrap();
            
                    Ok(res)
                }
            })

so i think in next version you should make public the second argument of the inner closure of .wrap() method.
