[][src]Struct h2::server::Connection

#[must_use = "streams do nothing unless polled"]
pub struct Connection<T, B: IntoBuf> { /* fields omitted */ }

Accepts inbound HTTP/2.0 streams on a connection.

A Connection is backed by an I/O resource (usually a TCP socket) and implements the HTTP/2.0 server logic for that connection. It is responsible for receiving inbound streams initiated by the client as well as driving the internal state forward.

Connection values are created by calling handshake. Once a Connection value is obtained, the caller must call poll or poll_close in order to drive the internal connection state forward.

See module level documentation for more details

Examples

server::handshake(my_io)
    .and_then(|server| {
        server.for_each(|(request, respond)| {
            // Process the request and send the response back to the client
            // using `respond`.
        })
    })

Methods

impl<T, B> Connection<T, B> where
    T: AsyncRead + AsyncWrite,
    B: IntoBuf
[src]

pub fn set_target_window_size(&mut self, size: u32)[src]

Sets the target window size for the whole connection.

If size is greater than the current value, then a WINDOW_UPDATE frame will be immediately sent to the remote, increasing the connection level window by size - current_value.

If size is less than the current value, nothing will happen immediately. However, as window capacity is released by ReleaseCapacity instances, no WINDOW_UPDATE frames will be sent out until the number of "in flight" bytes drops below size.

The default value is 65,535.

See ReleaseCapacity documentation for more details.

pub fn poll_close(&mut self) -> Poll<(), Error>[src]

Returns Ready when the underlying connection has closed.

If any new inbound streams are received during a call to poll_close, they will be queued and returned on the next call to poll.

This function will advance the internal connection state, driving progress on all the other handles (e.g. RecvStream and SendStream).

See here for more details.

pub fn abrupt_shutdown(&mut self, reason: Reason)[src]

Sets the connection to a GOAWAY state.

Does not terminate the connection. Must continue being polled to close connection.

After flushing the GOAWAY frame, the connection is closed. Any outstanding streams do not prevent the connection from closing. This should usually be reserved for shutting down when something bad external to h2 has happened, and open streams cannot be properly handled.

For graceful shutdowns, see graceful_shutdown.

pub fn graceful_shutdown(&mut self)[src]

Starts a graceful shutdown process.

Must continue being polled to close connection.

It's possible to receive more requests after calling this method, since they might have been in-flight from the client already. After about 1 RTT, no new requests should be accepted. Once all active streams have completed, the connection is closed.

pub fn ping_pong(&mut self) -> Option<PingPong>[src]

Takes a PingPong instance from the connection.

Note

This may only be called once. Calling multiple times will return None.
