A bitset is a compact structure to store a set of integers.

val empty : t

A bitset encoding the empty set.

mem field i returns true iff i has been added in field.

This functions returns Invalid_input i if i is negative.

add field i returns a new bitset which contains i in addition to the previous integers of field.

This functions returns Invalid_input i if i is negative.

from_list positions folds add over the positions starting from empty. This function returns Invalid_input i if i is negative and appears in positions.

val inter : t -> t -> t

inter set_l set_r returns set which is result of the intersection of set_l and set_r.

val diff : t -> t -> t

diff set_l set_r returns a set containing fiels in set_l that are not in set_r.

val occupied_size_in_bits : t -> int

occupied_size_in_bits bitset returns the current number of bits occupied by the bitset.
