Struct futures_util::io::WriteHalf

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

Available on crate feature io only.

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.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
