can hyper provider a function like golang hijack?

i try to rewrite some golang code in rust.

but I found that it would be inconvenient to implement without an api like golang hijack

If the request tried to do an HTTP/1.1 Upgrade, then a similar thing can be found in hyper::upgrade::on(req), which if you send back a 101 response, it will give you the tcpstream.
