Struct Sink

pub struct Sink { /* private fields */ }

A writer that consumes and drops all data.

This writer is constructed by the sink function. See its documentation for more.

Trait Implementations

impl Debug for Sink

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

Formats the value using the given formatter.

impl Write for Sink

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

Attempt to write bytes from buf into the object.

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

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

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

Attempt to close the object.

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

Attempt to write bytes from bufs into the object using vectored IO operations.

fn write<'a>(&'a mut self, buf: &'a [u8]) -> ImplFuture<Result<usize>>

where Self: Unpin,

Writes some bytes into the byte stream.

fn flush(&mut self) -> ImplFuture<Result<()>>

where Self: Unpin,

Flushes the stream to ensure that all buffered contents reach their destination.

fn write_vectored<'a>( &'a mut self, bufs: &'a [IoSlice<'a>], ) -> ImplFuture<Result<usize>>

where Self: Unpin,

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

fn write_all<'a>(&'a mut self, buf: &'a [u8]) -> ImplFuture<Result<()>>

where Self: Unpin,

Writes an entire buffer into the byte stream.

fn write_fmt<'a>(&'a mut self, fmt: Arguments<'_>) -> ImplFuture<Result<()>>

where Self: Unpin,

Writes a formatted string into this writer, returning any error encountered.
