Data.Functor.Classes.Generic.Internal

Internal functionality for Data.Functor.Classes.Generic.

This is an internal module and, as such, the API is not guaranteed to remain the same between any given release.

Fields

• ghc8ShowBehavior :: Bool

  If True, a default Show1 implementation will show hash signs (#) when showing unlifted types.

defaultOptions :: Options

Options that match the behavior of the installed version of GHC.

latestGHCOptions :: Options

Options that match the behavior of the most recent GHC release.

Eq1

liftEqDefault :: (GEq1 NonV4 (Rep1 f), Generic1 f) => (a -> b -> Bool) -> f a -> f b -> Bool

liftEqOptions :: (GEq1 NonV4 (Rep1 f), Generic1 f) => Options -> (a -> b -> Bool) -> f a -> f b -> Bool
