tuple-map

This library provides iterator-like utility methods like map, fold, for_each, and etc., for tuple.

Example

extern crate tuple_map;
use tuple_map::*;
fn main() {
    let (x, y) = (3, 4);
    let (x, y) = (x, y).map(|a| a + 5);
    assert_eq!(x, 8);
    assert_eq!(y, 9);
    
    let v = (3, 4, 5, 6).fold(vec![], |mut v, x| {
        if x % 3 == 0 {
            v.push(x);
        }
        v
    });
    assert_eq!(v, vec![3, 6]);
    
    assert!((3, 3, 3).same());
    
    assert_eq!((3, 4, 5).nth(1), Some(4));
}
