An async writer which will move data into the void.

This struct is generally created by calling sink. Please see the documentation of sink() for more details.

This is an asynchronous version of std::io::Sink.

Trait Implementations

impl AsyncWrite for Sink

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

Attempt to write bytes from buf into the object.

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

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

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

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

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

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

impl Debug for Sink

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
