unzip-n
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]);
}
