Struct tokio::io::ReadHalf

[+] Show declaration

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

[−] Expand description

The readable half of a value returned from 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.

pub fn unsplit(self, wr: WriteHalf<T>) -> T[−]

Reunites with a previously split WriteHalf.

Panics

If this ReadHalf and the given WriteHalf do not originate from the same split operation this method will panic. This can be checked ahead of time by comparing the stream ID of the two halves.

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

Attempts to read from the AsyncRead into buf.

fn poll_read_buf<B: BufMut>(
    self: Pin<&mut Self>,
    cx: &mut Context,
    buf: &mut B
) -> Poll<Result<usize>>[−]

Pulls some bytes from this source into the specified BufMut, returning how many bytes were read.

unsafe fn prepare_uninitialized_buffer(
    &self,
    buf: &mut [MaybeUninit<u8>]
) -> bool[−]

Prepares an uninitialized buffer to be safe to pass to read. Returns true if the supplied buffer was zeroed out.
