type alias Set counter id =

Dict counter id ()

A set type for IDs, is equal to a `ID.Dict' with empty tuples as values

empty : Set () (ID a)

fromList : List (ID a) -> Set () (ID a)

Create a set from a list of IDs

toList : Set counter (ID a) -> List (ID a)

isEmpty : Set counter (ID a) -> Bool

size : Set counter (ID a) -> Int

member : ID a -> Set counter (ID a) -> Bool

insert : ID a -> Set counter (ID a) -> Set counter (ID a)

Alias for `ID.Dict.insert' but without a value

remove : ID a -> Set counter (ID a) -> Set counter (ID a)

fold : (ID a -> c -> c) -> c -> Set counter (ID a) -> c

Alias for `ID.Dict.fold' but without a value argument

diff : Set counter1 (ID a) -> Set counter2 (ID a) -> Set counter1 (ID a)

intersect : Set counter1 (ID a) -> Set counter2 (ID a) -> Set counter1 (ID a)

union : Set counter1 (ID a) -> Set counter2 (ID a) -> Set () (ID a)
