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.

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