Struct async_pipe::PipeWriter

pub struct PipeWriter { /* fields omitted */ }

The write half of the pipe which implements AsyncWrite.

Methods

impl PipeWriter

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 and consumed by the reader; Otherwise it returns false.

Trait Implementations

impl AsyncWrite for PipeWriter

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

Attempt to write bytes from buf into the object.

fn poll_flush(self: Pin<&mut Self>, _cx: &mut Context) -> Poll<Result<()>>

Attempts to flush the object, ensuring that any buffered data reach their destination.

fn poll_shutdown(self: Pin<&mut Self>, _cx: &mut Context) -> Poll<Result<()>>

Initiates or attempts to shut down this writer, returning success when the I/O connection has completely shut down.

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

Writes a Buf into this value, returning how many bytes were written.

impl Drop for PipeWriter

fn drop(&mut self)

Executes the destructor for this type.
