pub fn quick_sort<T>(arr: &mut [T], compare_func: Le<T>)
Quicksort. Sorts a mut vector in place.
Has worst case O(n^2) performance, average case O(n log n). This is an unstable sort.
Prefix searches with a type followed by a colon (e.g.
fn:) to restrict the search to a given type.
Accepted types are: fn, mod,
struct (or str), enum,
trait, typedef (or
tdef).
