Function iter_num_tools::lerp_usize_iter

pub fn lerp_usize_iter<T>(
    from: RangeInclusive<usize>, 
    to: RangeInclusive<T>, 
    over: impl IntoIterator<Item = usize>
) -> impl Iterator<Item = T> where
    T: FromPrimitive + Mul<Output = T> + Sub<Output = T> + Add<Output = T> + Div<Output = T> + Copy, 

A convenient wrapper of over.into_iter().map(lerp_usize_fn(from, to)). See lerp_usize_fn
