[][src]Crate unzip_n

travis crates.io docs.rs

Procedural macro for unzipping iterators-over-n-length-tuples into n collections.

Here's a brief example of what it is capable of:

use unzip_n::unzip_n;

unzip_n!(pub 3);
// // Or simply leave the visibility modifier absent for inherited visibility
// // (which usually means "private").
// unzip_n!(3);

fn main() {
    let v = vec![(1, 2, 3), (4, 5, 6)];
    let (v1, v2, v3) = v.into_iter().unzip_n_vec();

    assert_eq!(v1, &[1, 4]);
    assert_eq!(v2, &[2, 5]);
    assert_eq!(v3, &[3, 6]);

Generates a trait and its implementation to "unzip" an iterator of N-sized tuple into N collections, where N is passed to the macro, like unzip_n(10):


A no-std version of the unzip_n macro, i.e. without the unzip_n_vec trait method.
