Names set type
Manipulating these sets
unitNameSet :: Name -> NameSet Source #
unionNameSets :: [NameSet] -> NameSet Source #
nameSetElems :: NameSet -> [Name] Source #
isEmptyNameSet :: NameSet -> Bool Source #
foldNameSet :: (Name -> b -> b) -> b -> NameSet -> b Source #
intersectsNameSet :: NameSet -> NameSet -> Bool Source #
True if there is a non-empty intersection.
s1 doesn't compute intersectsNameSet s2s2 if s1 is empty
nameSetElemsStable :: NameSet -> [Name] Source #
Get the elements of a NameSet with some stable ordering. This only works for Names that originate in the source code or have been tidied. See Note [Deterministic UniqFM] to learn about nondeterminism
Free variables
Manipulating sets of free variables
isEmptyFVs :: NameSet -> Bool Source #
Defs and uses
type DefUse = (Maybe Defs, Uses) Source #
(Just ds, us) => The use of any member of the ds
implies that all the us are used too.
Also, us may mention ds.
Nothing => Nothing is defined in this group, but
nevertheless all the uses are essential.
Used for instance declarations, for example
