Struct PlainIo 

pub struct PlainIo { /* private fields */ }

A portable fallback backend over a plain (connected) UDP socket.

Implementations

impl PlainIo

pub fn new(socket: UdpSocket) -> PlainIo

Wrap a connected UDP socket.

Trait Implementations

impl DataPlaneIo for PlainIo

fn send_batch(&mut self, datagrams: &[&[u8]]) -> Result<usize>

Send up to datagrams.len() datagrams in one sendmmsg(2) syscall.

Returns the number of datagrams accepted by the kernel (≤ input length).

fn recv_batch( &mut self, bufs: &mut [[u8; 2048]], lens: &mut [usize], ) -> Result<usize>

Receive up to bufs.len() datagrams in one recvmmsg(2) syscall.

Writes per-datagram byte counts into lens and returns the number of datagrams received (may be less than bufs.len()).

fn backend(&self) -> Backend

The backend actually selected at startup (after probing/fallback).

fn send(&mut self, datagram: &[u8]) -> Result<()>

Send one datagram.

fn recv(&mut self, buf: &mut [u8]) -> Result<usize>

Receive one datagram into buf, returning its length.
