1.2.0

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());
