Struct futures_util::io::ReadHalf

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

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

Implementations

impl<T> ReadHalf<T>

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

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

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.

impl<T: Debug> Debug for ReadHalf<T>

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

Formats the value using the given formatter.
