1.59.0 · source · pub fn zip<A, B>(
a: A,
b: B,
) -> Zip<<A as IntoIterator>::IntoIter, <B as IntoIterator>::IntoIter> ⓘwhere
A: IntoIterator,

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());
