Trait Implementations

impl AsyncWrite for Sink[+]

[+] Show hidden undocumented items

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_vectored(
    self: Pin<&mut Self>,
    cx: &mut Context<'_>,
    bufs: &[IoSlice<'_>]
) -> Poll<Result<usize, Error>>[−]

Like poll_write, except that it writes from a slice of buffers.

fn is_write_vectored(&self) -> bool[−]

Determines if this writer has an efficient poll_write_vectored implementation.

impl Debug for Sink[+]

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

Formats the value using the given formatter.
