zip-fill - Iterator Library

Crate registry

Documentation

Zip two iterators, if they have different length, the shortest is extended using a default value.

The two iterators must have the same Item type.

It is similar to zip_longest algorithm from the itertool python library.

Example

use zip_fill::ZipFill;
let a = [ 1, 2, 3, 4];
let b = [ 1, 2];
let z: Vec<_> = a.iter().zip_longest(&b, &0).collect();
assert_eq!(vec!((&1, &1), (&2, &2), (&3, &0), (&4, &0)), z);
let z: Vec<_> = zip_fill::zip_longest_with(&a, &b, &0, |a, b| a + b).collect();
assert_eq!(vec!(2, 4, 3, 4), z);
