GHC.Types.Unique.DSet

Description

Specialised deterministic sets, for things with Uniques

Based on UniqDFMs (as you would expect). See Note [Deterministic UniqFM] in GHC.Types.Unique.DFM for explanation why we need it.

Basically, the things need to be in class Uniquable.

Methods

(==) :: UniqDSet a -> UniqDSet a -> Bool #

(/=) :: UniqDSet a -> UniqDSet a -> Bool #

pprUniqDSet :: (a -> SDoc) -> UniqDSet a -> SDoc Source #

Manipulating these sets

nonDetStrictFoldUniqDSet :: (a -> b -> b) -> b -> UniqDSet a -> b Source #

mapUniqDSet :: Uniquable b => (a -> b) -> UniqDSet a -> UniqDSet b Source #

strictFoldUniqDSet :: (a -> r -> r) -> r -> UniqDSet a -> r Source #

mapMUniqDSet :: (Monad m, Uniquable b) => (a -> m b) -> UniqDSet a -> m (UniqDSet b) Source #

Like mapUniqDSet but for mapM. Assumes the function we are mapping over the UniqDSet does not modify uniques, as per Note [UniqSet invariant] in GHC.Types.Unique.Set.
