Expand description

Borrowed read half of Stream, created by Stream::split.

Implementations

source

impl<'a> ReadHalf<'a>

source

pub async fn peek(&self, buf: &mut [u8]) -> Result<usize>

Receives data on the socket from the remote address to which it is connected, without removing that data from the queue. On success, returns the number of bytes peeked.

source

pub fn poll_peek(
 &self,
 cx: &mut Context<'_>,
 buf: &mut ReadBuf<'_>
) -> Poll<Result<usize>>

Attempts to receive data on the socket, without removing that data from the queue, registering the current task for wakeup if data is not yet available.
