val compare_cardinal_with : t -> int -> int

compare_cardinal_with s n is equivalent to compare (cardinal s) n but runs in O(min(n, cardinal s)) time instead of O(cardinal s).

val to_list_bounded : int -> t -> elt list option

to_list_bounded n s returns Some l if s has at most n elements, where l is the sorted list of all elements. Returns None if s has more than n elements. Traverses at most n+1 elements.
