Struct PipeWriter

pub struct PipeWriter { /* private fields */ }

The write half of the pipe which implements AsyncWrite.

Implementations

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, Self: Sized,

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.
