Struct pal_async::unix::pipe::WriteHalf

pub struct WriteHalf { /* private fields */ }

The write half of a file, via PolledPipe::split.

Implementations

impl WriteHalf

pub fn get(&self) -> &File

Gets a reference to the inner file.

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 file is ready for write.

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

Trait Implementations

impl AsyncWrite for WriteHalf

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

Attempt to write bytes from buf into the object.

fn poll_flush(self: Pin<&mut Self>, cx: &mut Context<'_>) -> Poll<Result<()>>

Attempt to flush the object, ensuring that any buffered data reach their destination.

fn poll_close(self: Pin<&mut Self>, _cx: &mut Context<'_>) -> Poll<Result<()>>

Attempt to close the object.

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

Attempt to write bytes from bufs into the object using vectored IO operations.

impl PollReady for WriteHalf

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

Polls an object for readiness.
