Struct pal_async::socket::ReadHalf

pub struct ReadHalf<T> { /* private fields */ }

The read half of a socket, via PolledSocket::split.

Implementations

impl<T> ReadHalf<T>

pub fn get(&self) -> &T

Gets a reference to the inner socket.

pub fn poll_io<F, R>(&mut self, cx: &mut Context<'_>, f: F) -> Poll<Result<R>>

where F: FnMut(&mut Self) -> Result<R>,

Calls nonblocking operation f when the socket is ready for read.

If f returns Err(err) with err.kind() == io::ErrorKind::WouldBlock, then this re-polls the socket for readiness and returns Poll::Pending.

Trait Implementations

impl<T: AsSockRef> AsyncRead for ReadHalf<T>

fn poll_read( self: Pin<&mut Self>, cx: &mut Context<'_>, buf: &mut [u8], ) -> Poll<Result<usize>>

Attempt to read from the AsyncRead into buf.

fn poll_read_vectored( self: Pin<&mut Self>, cx: &mut Context<'_>, bufs: &mut [IoSliceMut<'_>], ) -> Poll<Result<usize>>

Attempt to read from the AsyncRead into bufs using vectored IO operations.

impl<T: AsSockRef> PollReady for ReadHalf<T>

fn poll_ready( &mut self, cx: &mut Context<'_>, events: PollEvents, ) -> Poll<PollEvents>

Polls an object for readiness.
