# Function core::iter::empty [−] [src]

    pub fn empty<T>() -> Empty<T>

Creates an iterator that yields nothing.

# Examples

Basic usage:

fn main() { use std::iter; // this could have been an iterator over i32, but alas, it's just not. let mut nope = iter::empty::<i32>(); assert_eq!(None, nope.next()); }

    use std::iter;

    // this could have been an iterator over i32, but alas, it's just not.
    let mut nope = iter::empty::<i32>();

    assert_eq!(None, nope.next());

## 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`)
