Function rdx::ska_sort::delegate_sort

pub fn delegate_sort<T, E, K>(
    extract_key: E, 
    arr: &mut [T], 
    depth: isize, 
    _iter: usize, 
    force: bool
) -> bool where
    E: Fn(&T) -> K,
    K: RadixSortKey, 

Delegate small sorts to sorting functions more optimized for them, returning true. Otherwise, return false
