runtimeRepLevity_maybe :: RuntimeRepType -> Maybe Levityghc GHC.Plugins Check whether a type (usually of kind RuntimeRep) is lifted, unlifted, or unknown. Returns Nothing if the type isn't of kind RuntimeRep. `runtimeRepLevity_maybe rr` returns:
sORTKind_maybe :: Kind -> Maybe (TypeOrConstraint, Type)ghc GHC.Plugins No documentation available.
setNominalRole_maybe :: Role -> Coercion -> Maybe CoercionNghc GHC.Plugins Converts a coercion to be nominal, if possible. See Note [Role twiddling functions]
splitAppCo_maybe :: Coercion -> Maybe (Coercion, Coercion)ghc GHC.Plugins Attempt to take a coercion application apart.
splitAppTyNoView_maybe :: HasDebugCallStack => Type -> Maybe (Type, Type)ghc GHC.Plugins Does the AppTy split as in splitAppTy_maybe, but assumes that any coreView stuff is already done
splitAppTy_maybe :: Type -> Maybe (Type, Type)ghc GHC.Plugins Attempt to take a type application apart, whether it is a function, type constructor, or plain type application. Note that type family applications are NEVER unsaturated by this!
splitCastTy_maybe :: Type -> Maybe (Type, Coercion)ghc GHC.Plugins No documentation available.
splitForAllCoVar_maybe :: Type -> Maybe (CoVar, Type)ghc GHC.Plugins Like splitForAllTyCoVar_maybe, but only returns Just if it is a covar binder.
splitForAllCo_co_maybe :: Coercion -> Maybe (CoVar, ForAllTyFlag, ForAllTyFlag, Coercion, Coercion)ghc GHC.Plugins Like splitForAllCo_maybe, but only returns Just for covar binder
splitForAllCo_maybe :: Coercion -> Maybe (TyCoVar, ForAllTyFlag, ForAllTyFlag, Coercion, Coercion)ghc GHC.Plugins No documentation available.
