### Important traits for Empty

`impl Read for Empty`

    pub fn empty() -> Empty

Constructs a new handle to an empty reader.

All reads from the returned reader will return `Ok``(0)`.

# Examples

A slightly sad example of not reading anything into a buffer:

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

    let mut buffer = String::new();
    io::empty().read_to_string(&mut buffer).unwrap();
    assert!(buffer.is_empty());Run

## 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`)
