An iterator adaptor for Rust that accumulates the elements from the base iterator using the provided closure.

Example

use iter_accumulate::IterAccumulate;

let input = [1, 2, 3, 4, 5];
let mut iter = input.iter().accumulate(1, |acc, i| acc * i);

assert_eq!(iter.next(), Some(1));
assert_eq!(iter.next(), Some(2));
assert_eq!(iter.next(), Some(6));
assert_eq!(iter.next(), Some(24));
assert_eq!(iter.next(), Some(120));
assert_eq!(iter.next(), None);
