Struct Gate 

pub struct Gate { /* private fields */ }

A UDP socket that hands quinn only the datagrams the gate admits.

Everything except [AsyncUdpSocket::poll_recv] is passed straight through, including the capability answers — max_receive_segments decides whether GRO is used at all and may_fragment decides whether MTU discovery runs, so a wrapper that answered them itself would quietly change the transport.

Implementations

impl Gate

pub fn new( inner: Arc<dyn AsyncUdpSocket>, expected: Expected, crypto: Arc<dyn ServerConfig>, ) -> Self

Wraps inner, judging against expected.

Trait Implementations

impl AsyncUdpSocket for Gate

fn create_io_poller(self: Arc<Self>) -> Pin<Box<dyn UdpPoller>>

Create a [UdpPoller] that can register a single task for write-readiness notifications

fn try_send(&self, transmit: &Transmit<'_>) -> Result<()>

Send UDP datagrams from transmits, or return WouldBlock and clear the underlying socket’s readiness, or return an I/O error

fn poll_recv( &self, cx: &mut Context<'_>, bufs: &mut [IoSliceMut<'_>], metas: &mut [RecvMeta], ) -> Poll<Result<usize>>

Receive UDP datagrams, or register to be woken if receiving may succeed in the future

fn local_addr(&self) -> Result<SocketAddr>

Look up the local IP address and port used by this socket

fn max_transmit_segments(&self) -> usize

Maximum number of datagrams that a [Transmit] may encode

fn max_receive_segments(&self) -> usize

Maximum number of datagrams that might be described by a single [RecvMeta]

fn may_fragment(&self) -> bool

Whether datagrams might get fragmented into multiple parts

impl Debug for Gate

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Hand-written because neither the crypto configuration the judge holds nor the trait object holding it is Debug, and AsyncUdpSocket requires one.
