I've seen several people run into this bug, so I requested prioritization.

#79810 (comment):

This resolves the crash in issue #79783. However, I haven't been able to come up with a minimal reproduction yet, so I'm leaving that issue open for now.

So this just needs a test to be closed.

I have try to compile the code:

let _bind_str = format! ("0.0.0.0:{}", 2233);
match HttpServer::new (|| {
    App::new ()
}).bind (&_bind_str [..]) {
    Ok (mut _server) => { _server.run ().await; () },
    Err (_e) => println! ("http listen failed: {}", _e.to_string ()),
};

but still catch question,

impl ServiceModule for Http {
    async fn async_entry (&self) {
        // if that code in there, I can't compile
    }
}
