# Function ethcore_util::standard::io::sink 1.0.0 [−] [src]

    pub 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);

## Search Tricks

Prefix searches with a type followed by a colon (e.g. `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g. `vec -> usize` or `* -> vec`)
