  2. TcRnCannotDeriveInstance :: Class -> [Type] -> !Maybe (DerivStrategy GhcTc) -> UsingGeneralizedNewtypeDeriving -> DeriveInstanceErrReason -> TcRnMessage

    ghc GHC.Tc.Errors.Types

    TcRnCannotDeriveInstance is an error that occurs every time a typeclass instance can't be derived. The DeriveInstanceErrReason will contain the specific reason this error arose. Example(s): None.

  6. isDerivedOccName :: OccName -> Bool

    ghc GHC.Types.Name.Occurrence

    Test for definitions internally generated by GHC. This predicate is used to suppress printing of internal definitions in some debug prints

  7. entityDerives :: EntityDef -> ![Text]

    persistent Database.Persist.EntityDef.Internal

    A list of type classes that have been derived for this entity.

  8. mpsDeriveInstances :: MkPersistSettings -> [Name]

    persistent Database.Persist.TH

    Automatically derive these typeclass instances for all record and key types. Default: []

  9. mpsDeriveInstances :: MkPersistSettings -> [Name]

    persistent Database.Persist.TH.Internal

    Automatically derive these typeclass instances for all record and key types. Default: []

  10. unsafeDerive :: Coercible n o => (o -> n) -> t o :- t n

    constraints Data.Constraint.Unsafe

    Coerce a dictionary unsafely from one type to a newtype of that type
