1. DerivErrBadConCovariant :: DataCon -> DeriveInstanceBadConstructor

   ghc	GHC.Tc.Errors.Types

   The given DataCon must not use the type variable in a function argument"

2. DerivErrBadConExistential :: DataCon -> DeriveInstanceBadConstructor

   ghc	GHC.Tc.Errors.Types

   The given DataCon must be truly polymorphic in the last argument of the data type.

3. DerivErrBadConFunTypes :: DataCon -> DeriveInstanceBadConstructor

   ghc	GHC.Tc.Errors.Types

   The given DataCon must not contain function types

4. DerivErrBadConHasConstraints :: DataCon -> DeriveInstanceBadConstructor

   ghc	GHC.Tc.Errors.Types

   The given DataCon has constraints in its type.

5. DerivErrBadConHasExistentials :: DataCon -> DeriveInstanceBadConstructor

   ghc	GHC.Tc.Errors.Types

   The given DataCon has existentials type vars in its type.

6. DerivErrBadConHasHigherRankType :: DataCon -> DeriveInstanceBadConstructor

   ghc	GHC.Tc.Errors.Types

   The given DataCon has a higher-rank type.

7. DerivErrBadConIsGADT :: DataCon -> DeriveInstanceBadConstructor

   ghc	GHC.Tc.Errors.Types

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

8. DerivErrBadConWrongArg :: DataCon -> DeriveInstanceBadConstructor

   ghc	GHC.Tc.Errors.Types

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

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

   ghc	GHC.Tc.Errors.Types

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

10. DerivErrBootFileFound :: DeriveInstanceErrReason

    ghc	GHC.Tc.Errors.Types

    No documentation available.
