Struct WriteHalf

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

The writable half of an object returned from AsyncRead::split.

Implementations

impl<T: AsyncRead + AsyncWrite> WriteHalf<T>

pub fn unsplit(self, r: ReadHalf<T>) -> T

Reunite with a previously split ReadHalf.

panics

If this WriteHalf and the given ReadHalf do not originate from the same AsyncRead::split operation this method will panic.

Trait Implementations

impl<T: AsyncWrite> AsyncWrite for WriteHalf<T>

fn shutdown(&mut self) -> Poll<(), Error>

Initiates or attempts to shut down this writer, returning success when the I/O connection has completely shut down.

fn write_buf<B: Buf>(&mut self, buf: &mut B) -> Poll<usize, Error>

where Self: Sized,

Write a Buf into this value, returning how many bytes were written.

fn poll_write(&mut self, buf: &[u8]) -> Poll<usize, Error>

Attempt to write bytes from buf into the object.

fn poll_flush(&mut self) -> Poll<(), Error>

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

impl<T: Debug> Debug for WriteHalf<T>

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

Formats the value using the given formatter.

impl<T: AsyncWrite> Write for WriteHalf<T>

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

Writes a buffer into this writer, returning how many bytes were written.

fn flush(&mut self) -> Result<()>

Flushes this output stream, ensuring that all intermediately buffered contents reach their destination.

fn write_vectored(&mut self, bufs: &[IoSlice<'_>]) -> Result<usize, Error>

Like write, except that it writes from a slice of buffers.

fn is_write_vectored(&self) -> bool

🔬This is a nightly-only experimental API. (can_vector)

Determines if this Writer has an efficient write_vectored implementation.

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

Attempts to write an entire buffer into this writer.

fn write_all_vectored(&mut self, bufs: &mut [IoSlice<'_>]) -> Result<(), Error>

🔬This is a nightly-only experimental API. (write_all_vectored)

Attempts to write multiple buffers into this writer.

fn write_fmt(&mut self, fmt: Arguments<'_>) -> Result<(), Error>

Writes a formatted string into this writer, returning any error encountered.

fn by_ref(&mut self) -> &mut Self

where Self: Sized,

Creates a “by reference” adapter for this instance of Write.
