Struct tokio::io::WriteHalf

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

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

Methods

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

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> Debug for WriteHalf<T> where
    T: Debug, 

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

Formats the value using the given formatter.

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

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

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

fn write_buf<B>(&mut self, buf: &mut B) -> Result<Async<usize>, Error> where
    B: Buf,
    WriteHalf<T>: Sized, 

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

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

Attempt to write bytes from buf into the object.

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

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

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

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

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

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

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

Attempts to write an entire buffer into this writer.

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

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

Important traits for &'_ mut W

impl<'_, W> Write for &'_ mut W where
    W: Write + ?Sized, impl<'_, R> Read for &'_ mut R where
    R: Read + ?Sized, 

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

Creates a "by reference" adaptor for this instance of Write.
