Function inclusive_scan

pub fn inclusive_scan<T, F: Fn(T, T) -> T>(src: &[T], f: F, dst: &mut [T])
where
    T: Copy,

Apply the closure f to each neighbouring pair of elements in src, storing the result in dst. The first element is copied as-is, and the first result of calling f on the first two elements of src in stored in the second position of dst.

Panics

This method panics if the slices have different lengths.
