Documentation

tcInstDecls1 :: [LInstDecl Name] -> TcM (TcGblEnv, [InstInfo Name], [DerivInfo]) Source #

tcInstDeclsDeriv :: [DerivInfo] -> [LTyClDecl Name] -> [LDerivDecl Name] -> TcM (TcGblEnv, [InstInfo Name], HsValBinds Name) Source #

Use DerivInfo for data family instances (produced by tcInstDecls1), datatype declarations (TyClDecl), and standalone deriving declarations (DerivDecl) to check and process all derived class instances.

tcInstDecls2 :: [LTyClDecl Name] -> [InstInfo Name] -> TcM (LHsBinds Id) Source #
