  1. tyConAppFunTy_maybe :: HasDebugCallStack => TyCon -> [Type] -> Maybe Type

    ghc GHC.Plugins

    Return Just if this TyConApp should be represented as a FunTy

  2. tyConAppTyConPicky_maybe :: Type -> Maybe TyCon

    ghc GHC.Plugins

    Retrieve the tycon heading this type, if there is one. Does not look through synonyms.

  3. tyConAppTyCon_maybe :: Type -> Maybe TyCon

    ghc GHC.Plugins

    The same as fst . splitTyConApp We can short-cut the FunTy case

  4. typeLevity_maybe :: HasDebugCallStack => Type -> Maybe Levity

    ghc GHC.Plugins

    Tries to compute the Levity of the given type. Returns either a definite Levity, or Nothing if we aren't sure (e.g. the type is representation-polymorphic). Panics if the kind does not have the shape TYPE r.

  5. userTypeError_maybe :: Type -> Maybe ErrorMsgType

    ghc GHC.Plugins

    Is this type a custom user error? If so, give us the error message.

  6. wiredInNameTyThing_maybe :: Name -> Maybe TyThing

    ghc GHC.Plugins

    No documentation available.

  7. bitSizeMaybe :: Bits a => a -> Maybe Int

    ghc GHC.Prelude.Basic

    No documentation available.

  8. lookupGlobalOccRn_maybe :: WhichGREs GREInfo -> RdrName -> RnM (Maybe GlobalRdrElt)

    ghc GHC.Rename.Env

    No documentation available.

  9. lookupLocalOccRn_maybe :: RdrName -> RnM (Maybe Name)

    ghc GHC.Rename.Env

    No documentation available.

  10. lookupLocalOccThLvl_maybe :: Name -> RnM (Maybe (TopLevelFlag, ThLevel))

    ghc GHC.Rename.Env
