Struct futures_util::io::WriteHalf

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

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

Implementations

impl<T> WriteHalf<T>

pub fn is_pair_of(&self, other: &ReadHalf<T>) -> bool

Checks if this WriteHalf and some ReadHalf were split from the same stream.

impl<T: Unpin> WriteHalf<T>

pub fn reunite(self, other: ReadHalf<T>) -> Result<T, ReuniteError<T>>

Attempts to put the two “halves” of a split AsyncRead + AsyncWrite back together. Succeeds only if the ReadHalf<T> and WriteHalf<T> are a matching pair originating from the same call to AsyncReadExt::split.

Trait Implementations

impl<W: AsyncWrite> AsyncWrite for WriteHalf<W>

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_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.

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.

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

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

Formats the value using the given formatter.
