ResponseVersionAdaptCtx

rama::http::layer::version_adapter

Struct ResponseVersionAdaptCtx 

pub struct ResponseVersionAdaptCtx {
    pub version: Version,
    pub connect_protocol: Option<Protocol>,
    pub websocket_key: Option<SecWebSocketKey>,
}
Available on crate features http and std only.
Expand description

Request-derived state, captured before a request is sent, that a response may need in order to be translated back to the original request Version.

The motivating case is the WebSocket handshake: an HTTP/1 101 Switching Protocols accept carries Sec-WebSocket-Accept, which is a signature of the request’s Sec-WebSocket-Key. That key lives only on the request, so it cannot be reconstructed from an HTTP/2 200 response alone, it must be captured here.

Fields§

§version: Version

Original version the request had

§connect_protocol: Option<Protocol>

The Extended CONNECT / Upgrade application protocol the request asked for (e.g. websocket), if any. Captured from the request’s :protocol extension (HTTP/2/3 CONNECT) or Upgrade header (HTTP/1).

§websocket_key: Option<SecWebSocketKey>

The request’s Sec-WebSocket-Key, needed to recompute Sec-WebSocket-Accept when reconstructing an HTTP/1 WebSocket handshake response.
