Data.Functor.Classes.Generic.Internal

Description

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.

Synopsis

Options

newtype Options Source #

Options that further configure how the functions in Data.Functor.Classes.Generic should behave.

Constructors

Options 

Fields

defaultOptions :: Options Source #

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

latestGHCOptions :: Options Source #

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 Source #

A sensible default liftEq implementation for Generic1 instances.

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

Like liftEqDefault, but with configurable Options. Currently, the Options have no effect (but this may change in the future).

class GEq1 v t where Source #

Class of generic representation types that can be checked for equality.
