#[must_use = "futures do nothing unless polled"]pub struct Connection<T, S, E = Exec> where
    S: HttpService<Body>,  { /* fields omitted */ }

[−]

A future binding a connection with a Service.

Polling this future will drive HTTP forward.

Implementations

`impl<I, B, S, E> Connection<I, S, E> where S: HttpService<Body, ResBody = B>, S::Error: Into<Box<dyn StdError + Send + Sync>>, I: AsyncRead + AsyncWrite + Unpin, B: HttpBody + 'static, B::Error: Into<Box<dyn StdError + Send + Sync>>, E: H2Exec<S::Future, B>,` [src][−]

`pub fn graceful_shutdown(self: Pin<&mut Self>)`[src][−]

Start a graceful shutdown process for this connection.

This Connection should continue to be polled until shutdown can finish.

Note

This should only be called while the Connection future is still pending. If called after Connection::poll has resolved, this does nothing.

`pub fn into_parts(self) -> Parts<I, S>`[src][−]

Return the inner IO object, and additional information.

If the IO object has been "rewound" the io will not contain those bytes rewound. This should only be called after poll_without_shutdown signals that the connection is "done". Otherwise, it may not have finished flushing all necessary HTTP bytes.

Panics

This method will panic if this connection is using an h2 protocol.

`pub fn try_into_parts(self) -> Option<Parts<I, S>>`[src][−]

Return the inner IO object, and additional information, if available.

This method will return a None if this connection is using an h2 protocol.

`pub fn poll_without_shutdown( &mut self, cx: &mut Context<'_> ) -> Poll<Result<()>> where S: Unpin, S::Future: Unpin, B: Unpin,` [src][−]

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.

`pub fn without_shutdown(self) -> impl Future<Output = Result<Parts<I, S>>> where S: Unpin, S::Future: Unpin, B: Unpin,` [src][−]

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.

`pub fn with_upgrades(self) -> UpgradeableConnection<I, S, E> where I: Send,` [src][−]

Enable this connection to support higher-level HTTP upgrades.
