Documentation
freeT :: (BindStruct c n, Ord n) => Env n -> c -> Set (Bound n) Source
Collect the free Spec variables in a thing (level-1).
freeVarsT :: Ord n => KindEnv n -> Type n -> Set (Bound n) Source
Collect the free type variables in a type.
class FreeVarConT c where Source
Methods
freeVarConT :: Ord n => KindEnv n -> c n -> (Set (Bound n), Set (Bound n)) Source
Collect the free type variables and constructors used in a thing.
Instances
collectBound :: (BindStruct c n, Ord n) => c -> Set (Bound n) Source
Collect all the bound variables in a thing, independent of whether they are free or not.
collectBinds :: (BindStruct c n, Ord n) => c -> ([Bind n], [Bind n]) Source
Collect all the spec and exp binders in a thing.
A description of the binding structure of some type or expression.
Describes how a variable was bound.
class BindStruct c n | c -> n where Source
Methods
slurpBindTree :: c -> [BindTree n] Source
Instances
| BindStruct (TyCon n) n Source | |
| BindStruct (Type n) n Source |
isBoundExpWit :: BoundLevel -> Bool Source
Check if a boundlevel is expression or witness
boundLevelOfBindWay :: BindWay -> BoundLevel Source
Get the BoundLevel corresponding to a BindWay.
