Struct futures_util::io::ReadHalf

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

This is supported on crate feature io only.

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

Implementations

impl<T: Unpin> ReadHalf<T>

pub fn reunite(self, other: WriteHalf<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<R: AsyncRead> AsyncRead for ReadHalf<R>

fn poll_read(
    self: Pin<&mut Self>,
    cx: &mut Context<'_>,
    buf: &mut [u8]
) -> Poll<Result<usize>>

Attempt to read from the AsyncRead into buf.

fn poll_read_vectored(
    self: Pin<&mut Self>,
    cx: &mut Context<'_>,
    bufs: &mut [IoSliceMut<'_>]
) -> Poll<Result<usize>>

Attempt to read from the AsyncRead into bufs using vectored IO operations.

unsafe fn initializer(&self) -> Initializer

Determines if this AsyncReader can work with buffers of uninitialized memory.

impl<T: Debug> Debug for ReadHalf<T>

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

Formats the value using the given formatter.
