Function std::io::sink

pub const fn sink() -> Sink 

Creates an instance of a writer which will successfully consume all data.

All calls to write on the returned instance will return Ok(buf.len()) and the contents of the buffer will not be inspected.

Examples

use std::io::{self, Write};

let buffer = vec![1, 2, 3, 5, 8];
let num_bytes = io::sink().write(&buffer).unwrap();
assert_eq!(num_bytes, 5);
