pub fn zip<A, B>(a: A, b: B) -> Zip<A::IntoIter, B::IntoIter> ⓘwhere
A: IntoIterator,
B: IntoIterator,
Expand description
将参数转换为迭代器并压缩它们。

的文档。
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());
// 嵌套 zip 也可以:
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());
