Synopsis

union :: IntSet -> IntSet -> IntSet #

O(n+m). The union of two sets.

unions :: Foldable f => f IntSet -> IntSet #

The union of a list of sets.

member :: Key -> IntSet -> Bool #

O(min(n,W)). Is the value a member of the set?

empty :: IntSet #

O(1). The empty set.

delete :: Key -> IntSet -> IntSet #

O(min(n,W)). Delete a value in the set. Returns the original set when the value was not present.

singleton :: Key -> IntSet #

O(1). A set of one element.

fromList :: [Key] -> IntSet #

O(n*min(n,W)). Create a set from a list of integers.

toList :: IntSet -> [Key] #

O(n). Convert the set to a list of elements. Subject to list fusion.

toDescList :: IntSet -> [Key] #

O(n). Convert the set to a descending list of elements. Subject to list fusion.

isSubsetOf :: IntSet -> IntSet -> Bool #

O(n+m). Is this a subset? (s1 `isSubsetOf` s2) tells whether s1 is a subset of s2.

null :: IntSet -> Bool #

O(1). Is the set empty?

intersection :: IntSet -> IntSet -> IntSet #

O(n+m). The intersection of two sets.

difference :: IntSet -> IntSet -> IntSet #

O(n+m). Difference between two sets.
