# Function bitflags::__core::io::empty [−] [src]

    pub fn empty() -> Empty

1.0.0

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;
    use std::io::Read;

    let mut buffer = String::new();
    try!(io::empty().read_to_string(&mut buffer));

## 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`)
