pub struct Sink;
Expand description

A sink to which all writes succeed. See [std::io::Sink] for more info.

Created using io::sink().

Trait Implementations§

Source§

impl Write for Sink

Source§

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

Writes buf into this writer, returning how many bytes were written.
Source§

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

Attempts to write an entire buffer into this writer.
Source§

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

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