Can you move an App into an HttpServer::new?

Not a major issue, just a code style preference brought over from http frameworks I have used in other languages. I am wondering why I cannot move my App into HttpServer::new.

What I'd like to do is define my app like this:

#[tokio::main]
async fn main()  -> std::io::Result<()> {
  let mut app = App::new();
  
  app.route("/", web::get().to(manual_hello));
  app.route("/foo", web::get().to(handler_foo));
  app.route("/bar", web::get().to(handler_bar));

  HttpServer::new(move || app)
    .bind(("127.0.0.1", 8080))?.run().await
}

async fn manual_hello() -> impl Responder {
  HttpResponse::Ok().body("Hey there!")
}

However it appears that the trait Cloneis not implemented forApp<actix_web::app_service::AppEntry>`. Which I understand but I wonder if there is a way to use Actix with the pattern described above?

The closure passed to HttpServer::new is an app factory and App doesn't impl Clone so it's not possible to just clone the app into the re-usable closure.

You can however return an app from a function or use App::configure() to split up or share routing setups.
