Var, Id and TyVar set types
type VarSet = UniqSet Var Source #
A non-deterministic set of variables. See Note [Deterministic UniqFM] in UniqDFM for explanation why it's not deterministic and why it matters. Use DVarSet if the set eventually gets converted into a list or folded over in a way where the order changes the generated code, for example when abstracting variables.
type TyCoVarSet = UniqSet TyCoVar Source #
Manipulating these sets
emptyVarSet :: VarSet Source #
unitVarSet :: Var -> VarSet Source #
varSetElems :: VarSet -> [Var] Source #
unionVarSets :: [VarSet] -> VarSet Source #
mapUnionVarSet :: (a -> VarSet) -> [a] -> VarSet Source #
map the function over the list, and union the results
isEmptyVarSet :: VarSet -> Bool Source #
foldVarSet :: (Var -> a -> a) -> a -> VarSet -> a Source #
sizeVarSet :: VarSet -> Int Source #
pluralVarSet :: VarSet -> SDoc Source #
Determines the pluralisation suffix appropriate for the length of a set in the same way that plural from Outputable does for lists.
Arguments
| :: ([Var] -> SDoc) | The pretty printing function to use on the elements |
| -> VarSet | The things to be pretty printed |
| -> SDoc |
|
Pretty-print a non-deterministic set. The order of variables is non-deterministic and for pretty-printing that shouldn't be a problem. Having this function helps contain the non-determinism created with varSetElems.

dVarSetElems :: DVarSet -> [Var] Source #
unionDVarSets :: [DVarSet] -> DVarSet Source #
mapUnionDVarSet :: (a -> DVarSet) -> [a] -> DVarSet Source #
Map the function over the list, and union the results
isEmptyDVarSet :: DVarSet -> Bool Source #
foldDVarSet :: (Var -> a -> a) -> a -> DVarSet -> a Source #
sizeDVarSet :: DVarSet -> Int Source #
seqDVarSet :: DVarSet -> () Source #
partitionDVarSet :: (Var -> Bool) -> DVarSet -> (DVarSet, DVarSet) Source #
Partition DVarSet according to the predicate given
dVarSetToVarSet :: DVarSet -> VarSet Source #
Convert a DVarSet to a VarSet by forgeting the order of insertion
