`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).
