Struct async_pipe::PipeReader

pub struct PipeReader { /* fields omitted */ }

The read half of the pipe which implements AsyncRead.

Methods

impl PipeReader

pub fn close(&self) -> Result<()>

Closes the pipe, any further read will return EOF and any further write will raise an error.

pub fn is_flushed(&self) -> Result<bool>

It returns true if the next data chunk is written by the writer and consumed by the reader; Otherwise it returns false.

Trait Implementations

impl AsyncRead for PipeReader

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

Attempts to read from the AsyncRead into buf.

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.

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

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

impl Drop for PipeReader

fn drop(&mut self)

Executes the destructor for this type.
