type Kind = Type Source

The level above types

type KindOrType = Type Source

Either a Kind or a Type

type KiName = Name Kind Source

Reference to a Kind

type TyName = Name Type Source

Reference to a Type

type TyVar = Var Type Source

Type variable

tyView :: Type -> TypeView Source

An easier view on types

coreView :: HashMap TyConName TyCon -> Type -> TypeView Source

A view on types in which Signal types and newtypes are transparent, and type functions are evaluated when possible.

transparentTy :: Type -> Type Source

A transformation that renders Signal types transparent

typeKind :: HashMap TyConName TyCon -> Type -> Kind Source

Determine the kind of a type

mkTyConTy :: TyConName -> Type Source

Make a Type out of a TyCon

mkFunTy :: Type -> Type -> Type Source

Make a function type of an argument and result type

mkTyConApp :: TyConName -> [Type] -> Type Source

Make a TyCon Application out of a TyCon and a list of argument types

splitFunTy :: HashMap TyConName TyCon -> Type -> Maybe (Type, Type) Source

Split a function type in an argument and result type

splitFunTys :: HashMap TyConName TyCon -> Type -> ([Type], Type) Source

splitFunForallTy :: Type -> ([Either TyVar Type], Type) Source

Split a poly-function type in a: list of type-binders and argument types, and the result type

splitTyConAppM :: Type -> Maybe (TyConName, [Type]) Source

Split a TyCon Application in a TyCon and its arguments

isPolyFunTy :: Type -> Bool Source

Is a type a polymorphic or function type?

isPolyFunCoreTy :: HashMap TyConName TyCon -> Type -> Bool Source

Is a type a polymorphic or function type under coreView?

isPolyTy :: Type -> Bool Source

Is a type polymorphic?

isFunTy :: HashMap TyConName TyCon -> Type -> Bool Source

Is a type a function type?

applyFunTy :: HashMap TyConName TyCon -> Type -> Type -> Type Source

Apply a function type to an argument type and get the result type

applyTy :: Fresh m => HashMap TyConName TyCon -> Type -> KindOrType -> m Type Source

Substitute the type variable of a type (ForAllTy) with another type

findFunSubst :: [([Type], Type)] -> [Type] -> Maybe Type Source
