Macro combin_iterator::altern

macro_rules! altern {
    ($($params:expr $(,)?)*) => { ... };
}

The altern! macro provides a convenient syntax for creating an Altern iterator.

Syntax

The macro takes a variable number of iterator expressions, separated by commas. It then constructs an Altern instance and adds each provided iterator using the add method.

Examples

use std::vec;
use crate::altern;

let vec1 = vec![1, 4, 7, 9];
let vec2 = vec![2, 5];
let vec3 = vec![3, 6, 8];

// Using the altern! macro for concise syntax
let iter = altern!(vec1.iter(), vec2.iter(), vec3.iter());

// The iterator should yield the same results as adding iterators individually
assert_eq!(iter.collect::<Vec<_>>(), vec![&1, &2, &3, &4, &5, &6, &7, &8, &9]);
