rust-iterslide

This package implements "sliding window" functionality for any iterator over a Cloneable item.

Example

use iterslide::SlideIterator;

fn main() {
    let v: Vec<i8> = vec![1, 2, 3, 4, 5];

    for window in v.slide(3) {
        // window is a VecDeque<i8>
        println!("{:?}", window);
    }
}

Output:

[1, 2, 3]
[2, 3, 4]
[3, 4, 5]

Alternatives

• Rust's windows method for slices does what you would expect. This does no allocation. However, this is only implemented for slices.

• itertools' tuple_windows method returns a sliding window iterator over tuples instead of VecDeques. This saves a VecDeque allocation in construction of the iterator. However, tuple_windows is limited to window sizes of at most 4.
