Description
Collecting sets of variables and constructors.
- data BindTree n
- data BindWay
- data BoundLevel
- class BindStruct c n | c -> n where
- isBoundExpWit :: BoundLevel -> Bool
- boundLevelOfBindWay :: BindWay -> BoundLevel
- bindDefT :: BindStruct c n => BindWay -> [Bind n] -> [c] -> BindTree n
- freeT :: (BindStruct c n, Ord n) => Env n -> c -> Set (Bound n)
- freeOfTreeT :: Ord n => Env n -> BindTree n -> Set (Bound n)
- collectBound :: (BindStruct c n, Ord n) => c -> Set (Bound n)
- collectBinds :: (BindStruct c n, Ord n) => c -> ([Bind n], [Bind n])

Describes how a variable was bound.

Methods
slurpBindTree :: c -> [BindTree 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.
bindDefT :: BindStruct c n => BindWay -> [Bind n] -> [c] -> BindTree n Source #
Helper for constructing the BindTree for a type binder.
freeT :: (BindStruct c n, Ord n) => Env n -> c -> Set (Bound n) Source #
Collect the free Spec variables in a thing (level-1).
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.
