or-iterator

Rust 迭代器，接受两个迭代器并返回非空迭代器

use or_iterator::OrIterator;

let v1 = vec![1, 2, 3];
let v2 = vec![4, 5];
let or = v1.iter().or(v2.iter());
assert_eq!(3, or.count());

let v1 = vec![];
let v2 = vec![4, 5];
let or = v1.iter().or(v2.iter());
assert_eq!(2, or.count());

use or_iterator::OrIterator;

let v1 = vec![1, 2, 3];
let v2 = vec![4, 5];
let or = v1.iter().or(v2.iter());
assert_eq!(3, or.count());

let v1 = vec![];
let v2 = vec![4, 5];
let or = v1.iter().or(v2.iter());
assert_eq!(2, or.count());
