It's hard to return HttpServer or App<AppEntry, Body> from a function

[UkonnRa]

For some reason, I have to return HttpServer from a function (say consume a Config struct and generate a HttpServer). But the type signature of HttpServer is REALLY HARD for me to return, or even possible. Tons of depending types are private.

Even worse, so as actix_Web::App. App::new will return App<AppEntry, Body>, where AppEntry is private also... So it is still impossible to return from my function...

Finding that actix_web::Resource, actix_web::Scope are usable. So maybe I can return there types instead

Make sure that you remove semicolon inside closure where you call App::new(), otherwise App won't be returned from the closure.

Hope this from the FAQ helps future wanderers to this issue: How can I return App from a function / why is AppEntry private?
