Expand description

Iterate iterable with a particular value created by a function inserted between each element.

IntoIterator enabled version of Iterator::intersperse_with.

use itertools::intersperse_with;

let mut i = 10;
itertools::assert_equal(intersperse_with((0..3), || { i -= 1; i }), vec![0, 9, 1, 8, 2]);
assert_eq!(i, 8);
