Struct std::io::Sink

pub struct Sink { /* fields omitted */ }

A 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.

Trait Implementations

impl Write for Sink

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

Write a buffer into this writer, returning how many bytes were written.

fn write_vectored(&mut self, bufs: &[IoVec]) -> Result<usize>

🔬 This is a nightly-only experimental API. (iovec #58452)

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

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

Flush this output stream, ensuring that all intermediately buffered contents reach their destination.

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

Attempts to write an entire buffer into this writer.

fn write_fmt(&mut self, fmt: Arguments) -> Result<()>

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

fn by_ref(&mut self) -> &mut Self where

impl Debug for Sink

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

Formats the value using the given formatter.
