Struct hyper::client::conn::Connection

source · [−]

pub struct Connection<T, B> where
    T: AsyncRead + AsyncWrite + Send + 'static,
    B: HttpBody + 'static,  { /* private fields */ }

Available on crate feature client and (crate features http1 or http2) only.

Expand description

A future that processes all HTTP state for the IO object.

In most cases, this should just be spawned into an executor, so that it can process incoming and outgoing messages, notice hangups, and the like.

Implementations

source

impl<T, B> Connection<T, B> where
 T: AsyncRead + AsyncWrite + Unpin + Send + 'static,
 B: HttpBody + Unpin + Send + 'static,
 B::Data: Send,
 B::Error: Into<Box<dyn StdError + Send + Sync>>,

source

pub fn into_parts(self) -> Parts<T>

Return the inner IO object, and additional information.

Only works for HTTP/1 connections. HTTP/2 connections will panic.

source

pub fn poll_without_shutdown(
&mut self,
cx: &mut Context<'_>
) -> Poll<Result<()>>

Poll the connection for completion, but without calling shutdown on the underlying IO.

This is useful to allow running a connection while doing an HTTP upgrade. Once the upgrade is completed, the connection would be “done”, but it is not desired to actually shutdown the IO object. Instead you would take it back using into_parts.

Use poll_fn and try_ready! to work with this function; or use the without_shutdown wrapper.

source

pub fn without_shutdown(self) -> impl Future<Output = Result<Parts<T>>>

Prevent shutdown of the underlying IO object at the end of service the request, instead run into_parts. This is a convenience wrapper over poll_without_shutdown.

source

pub fn http2_is_extended_connect_protocol_enabled(&self) -> bool

Returns whether the extended CONNECT protocol is enabled or not.

This setting is configured by the server peer by sending the SETTINGS_ENABLE_CONNECT_PROTOCOL parameter in a SETTINGS frame. This method returns the currently acknowledged value received from the remote.
