Documentation
lookupLocalOccThLvl_maybe :: Name -> RnM (Maybe (TopLevelFlag, ThLevel)) Source #
lookupGlobalOccRn_overloaded :: Bool -> RdrName -> RnM (Maybe (Either Name [Name])) Source #
Like lookupOccRn_maybe, but with a more informative result if
the RdrName happens to be a record selector:
- Nothing -> name not in scope (no error reported)
- Just (Left x) -> name uniquely refers to x, or there is a name clash (reported)
- Just (Right xs) -> name refers to one or more record selectors; if overload_ok was False, this list will be a singleton.
lookupExactOcc :: Name -> RnM Name Source #
Lookup an Exact RdrName. See Note [Looking up Exact RdrNames].
This adds an error if the name cannot be found.
data ChildLookupResult Source #

lookupSubBndrOcc_helper :: Bool -> Bool -> Name -> RdrName -> RnM ChildLookupResult Source #
Used in export lists to lookup the children.
combineChildLookupResult :: [RnM ChildLookupResult] -> RnM ChildLookupResult Source #
Specialised version of msum for RnM ChildLookupResult
