Static File Example Question

[emnul]

Summary

I'm curious why in examples/static-file-server we serve the different Routers produced by using_* and the other functions on different ports:

    tokio::join!(
        serve(using_serve_dir(), 3001),
        serve(using_serve_dir_with_assets_fallback(), 3002),
        serve(using_serve_dir_only_from_root_via_fallback(), 3003),
        serve(using_serve_dir_with_handler_as_service(), 3004),
        serve(two_serve_dirs(), 3005),
        serve(calling_serve_dir_from_a_handler(), 3006),
        serve(using_serve_file_from_a_route(), 3307),
    );

Why would someone want to do this rather than use the same port for all of them?

I think the idea there is that it's really a couple of seperate but closely related examples that are simply packaged up as one binary.

That makes sense! I thought this was likely the case, but wasn't sure. Maybe a quick comment could be added to clarify?
