# iter_accumulate

An iterator adaptor for Rust that accumulates the elements from the base iterator

using the provided closure.

## Example

```rust

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);

```
