Expand description

Converts the arguments to iterators and zips them.

See the documentation of Iterator::zip for more.

Examples

use std::iter::zip;

let xs = [1, 2, 3];
let ys = [4, 5, 6];

let mut iter = zip(xs, ys);

assert_eq!(iter.next().unwrap(), (1, 4));
assert_eq!(iter.next().unwrap(), (2, 5));
assert_eq!(iter.next().unwrap(), (3, 6));
assert!(iter.next().is_none());

// Nested zips are also possible:
let zs = [7, 8, 9];

let mut iter = zip(zip(xs, ys), zs);

assert_eq!(iter.next().unwrap(), ((1, 4), 7));
assert_eq!(iter.next().unwrap(), ((2, 5), 8));
assert_eq!(iter.next().unwrap(), ((3, 6), 9));
assert!(iter.next().is_none());
