  1. DerivErrBadConHasConstraints :: DataCon -> DeriveInstanceBadConstructor

    ghc-lib-parser GHC.Tc.Errors.Types

    The given DataCon has constraints in its type.

  2. DerivErrBadConHasExistentials :: DataCon -> DeriveInstanceBadConstructor

    ghc-lib-parser GHC.Tc.Errors.Types

    The given DataCon has existentials type vars in its type.

  3. DerivErrBadConHasHigherRankType :: DataCon -> DeriveInstanceBadConstructor

    ghc-lib-parser GHC.Tc.Errors.Types

    The given DataCon has a higher-rank type.

  4. DerivErrBadConIsGADT :: DataCon -> DeriveInstanceBadConstructor

    ghc-lib-parser GHC.Tc.Errors.Types

    The given DataCon is a GADT so we cannot directly derive an istance for it.

  5. DerivErrBadConWrongArg :: DataCon -> DeriveInstanceBadConstructor

    ghc-lib-parser GHC.Tc.Errors.Types

    The given DataCon must use the type variable only as the last argument of a data type

  6. DerivErrBadConstructor :: !Maybe HasWildcard -> [DeriveInstanceBadConstructor] -> DeriveInstanceErrReason

    ghc-lib-parser GHC.Tc.Errors.Types

    We couldn't derive an instance for a particular data constructor for a variety of reasons.

  7. DerivErrBootFileFound :: DeriveInstanceErrReason

    ghc-lib-parser GHC.Tc.Errors.Types

    No documentation available.

  8. DerivErrCannotEtaReduceEnough :: Bool -> DeriveInstanceErrReason

    ghc-lib-parser GHC.Tc.Errors.Types

    No documentation available.

  9. DerivErrDataConsNotAllInScope :: TyCon -> DeriveInstanceErrReason

    ghc-lib-parser GHC.Tc.Errors.Types

    No documentation available.

  10. DerivErrDerivingViaWrongKind :: Kind -> Type -> Kind -> DeriveInstanceErrReason

    ghc-lib-parser GHC.Tc.Errors.Types

    No documentation available.
