lookupRecFieldOcc :: Maybe Name -> RdrName -> RnM Nameghc GHC.Rename.Env Look up an occurrence of a field in record construction or pattern matching (but not update). If -XDisambiguateRecordFields is off, then we will pass Nothing for the DataCon Name, i.e. we don't use the data constructor for disambiguation. See Note [DisambiguateRecordFields] and Note [NoFieldSelectors].
lookupRecUpdFields :: NonEmpty (LHsRecUpdField GhcPs GhcPs) -> RnM (NonEmpty (HsRecUpdParent GhcRn))ghc GHC.Rename.Env Returns all possible collections of field labels for the given record update. Example: data D = MkD { fld1 :: Int, fld2 :: Bool } data E = MkE1 { fld1 :: Int, fld2 :: Bool, fld3 :: Char } | MkE2 { fld1 :: Int, fld2 :: Bool } data F = MkF1 { fld1 :: Int } | MkF2 { fld2 :: Bool } f r = r { fld1 = a, fld2 = b } This function will return:
- [ D.fld1, D.fld2 -- could be a record update at type D , [ E.fld1, E.fld2 ] -- could be a record update at type E ] -- cannot be a record update at type F: no constructor has both -- of the fields fld1 and fld2
