How to impl hyper http2 https client support HTTPS_PROXY=http://127.0.0.1:1234?

I found hyper http2 https client working example.

https://users.rust-lang.org/t/http2-client-with-hyper/109617/4

Request: Request {
    method: GET,
    uri: https://api.github.com/repos/hyperium/hyper,
    version: HTTP/2.0,
    headers: {
        "user-agent": "hyper-client-http2",
    },
    body: Empty,
}
Response: Response {
    status: 200,
    version: HTTP/2.0,

But no idea how to support HTTPS_PROXY=http://127.0.0.1:1234.

I try

tokio::net::TcpStream::connect("127.0.0.1:1234".parse::<std::net::SocketAddr>().unwrap()).await?

Got

called `Result::unwrap()` on an `Err` value: Os { code: 104, kind: ConnectionReset, message: "Connection reset by peer" }

But proxy is OK

$ curl -v --no-progress-meter --http2-prior-knowledge -x 127.0.0.1:1234 https://api.github.com/repos/hyperium/hyper |& grep 'HTTP'
* CONNECT tunnel: HTTP/1.1 negotiated

That looks like what is listening on that local port is closing the connection on you. I'm not sure what else you might be doing in code.

Are you doing this to learn? Or do you just want it to work? Because reqwest provides working proxy support automatically.
