Struct Connection

Source
pub struct Connection<T, B>
where T: Read + Write, B: Body + 'static,
{ inner: Dispatcher<Client<B>, B, T, Client>, }
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.

Instances of this type are typically created via the handshake function

Implementations§

Source§

impl<T, B> Connection<T, B>
where T: Read + Write + Unpin, B: Body + 'static, 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 async fn without_shutdown(self) -> 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§

impl<T, B> Connection<T, B>
where T: Read + Write + Unpin + Send, B: Body + 'static, B::Error: Into<Box<dyn StdError + Send + Sync>>,

Source

pub fn with_upgrades(self) -> UpgradeableConnection<T, B>

Enable this connection to support higher-level HTTP upgrades.

See the upgrade module for more.
