`actix-web` automatically upgrades connections to _HTTP/2_ if possible.

<!-- TODO: use rustls example -->

|
|
When either of the `rustls` or `openssl` features are enabled, `HttpServer` provides the [`bind_rustls()`][bindrustls] method and [`bind_openssl()`][bindopenssl] methods, respectively.

Upgrades to HTTP/2 described in [RFC 7540 §3.2][rfcsection32] are not supported. Starting HTTP/2 with prior knowledge is supported for both cleartext and TLS connections ([RFC 7540 §3.4][rfcsection34]) (when using the lower level `actix-http` service builders).
