Platform

Description
there used to be the function hyper::service::make_service_fn

Now it's gone. There's no mention of it in the docs, no in the ChangeLog, nowhere. Where is it?

How to convert this into v1.0x?

    let sf = make_service_fn(|_connection| async {
        Ok::<_, Infallible>(service_fn(move |req| handle_post_req(req)))
    });
