Can I get the CN?

With an older version of Hyper using OpenSSL I could do something like this:

 if let Some(sslstream) = request.ssl::<SslStream<HttpStream>>() {
            let ssl: &Ssl = sslstream.ssl();
            let peer_x509: X509 = ssl.peer_certificate().unwrap();
            let sn = peer_x509.subject_name();
            cn = sn.text_by_nid(Nid::CN).unwrap();
            debug!("cn: {}", &cn);
        }

I need the CN to do anything useful on our corporate network.
Is it possible to do something like this when I'm using hyper-rustls?
If yes, how?

Thanks!

Start by examining the hyper-rustls integration and the OpenSSL example in the issue to determine whether the peer certificate and its CN are exposed. Done means identifying a supported way to obtain the CN, or documenting that this is not available through the integration.
