Struct `Protocol`

pub struct Protocol { /* private fields */ }

Extension type representing the :protocol pseudo-header in HTTP/2.

The Protocol extension allows access to the value of the :protocol pseudo-header used by the Extended CONNECT Protocol. This extension is only sent on HTTP/2 CONNECT requests, most commonly with the value websocket.

Example

use hyper::ext::Protocol;
use http::{Request, Method, Version};

let mut req = Request::new(());
*req.method_mut() = Method::CONNECT;
*req.version_mut() = Version::HTTP_2;
req.extensions_mut().insert(Protocol::from_static("websocket"));
// Now the request will include the `:protocol` pseudo-header with value "websocket"

Implementations
