Struct `Connection`

struct Connection<T, S> { ... }
where
    S: HttpService<crate::body::Incoming>

A Future representing an HTTP/1 connection, bound to a Service, returned from Builder::serve_connection.

To drive HTTP on this connection this future must be polled, typically with .await. If it isn't polled, no progress will be made on this connection.

Implementations

`impl<I, B, S> Connection<I, S>`

fn graceful_shutdown(self: Pin<&mut Self>)

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.

fn into_parts(self: Self) -> Parts<I, S>

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.

fn poll_without_shutdown(self: &mut Self, cx: &mut Context<'_>) -> Poll<crate::Result<()>> where S: Unpin, <S as >::Future: Unpin

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.

fn without_shutdown(self: Self) -> impl Future<Output = crate::Result<Parts<I, S>>>

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.

Error

This errors if the underlying connection protocol is not HTTP/1.

fn with_upgrades(self: Self) -> UpgradeableConnection<I, S> where I: Send

Enable this connection to support higher-level HTTP upgrades.

See the upgrade module for more.
