Struct UdpSocketState

pub struct UdpSocketState { /* private fields */ }

Tokio-compatible UDP socket with some useful specializations.

Unlike a standard tokio UDP socket, this allows ECN bits to be read and written on some platforms.

Implementations

impl UdpSocketState

pub fn new(sock: UdpSockRef<'_>) -> Result<Self>

pub fn send( &self, socket: UdpSockRef<'_>, transmit: &Transmit<'_>, ) -> Result<()>

pub fn recv( &self, socket: UdpSockRef<'_>, bufs: &mut [IoSliceMut<'_>], meta: &mut [RecvMeta], ) -> Result<usize>

pub fn max_gso_segments(&self) -> usize

The maximum amount of segments which can be transmitted if a platform supports Generic Send Offload (GSO).

This is 1 if the platform doesn’t support GSO. Subject to change if errors are detected while using GSO.

pub fn gro_segments(&self) -> usize

The number of segments to read when GRO is enabled. Used as a factor to compute the receive buffer size.

Returns 1 if the platform doesn’t support GRO.

pub fn may_fragment(&self) -> bool

Whether transmitted datagrams might get fragmented by the IP layer

Returns false on targets which employ e.g. the IPV6_DONTFRAG socket option.

Trait Implementations

impl Debug for UdpSocketState

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

Formats the value using the given formatter.
