Struct futures::io::WriteHalf

[+] Show declaration

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

[−] Expand description

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

Implementations

impl<T> WriteHalf<T> where
    T: Unpin, [−]

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.

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

Attempt to write bytes from buf into the object.

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

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

fn poll_flush(
    self: Pin<&mut WriteHalf<W>>,
    cx: &mut Context<'_>
) -> Poll<Result<(), Error>>[−]

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

fn poll_close(
    self: Pin<&mut WriteHalf<W>>,
    cx: &mut Context<'_>
) -> Poll<Result<(), Error>>[−]

Attempt to close the object.

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

Formats the value using the given formatter.
