Generic equality.

Generic equality

class HEq phi f where

Methods

heq :: (forall ix. phi ix -> r ix -> r ix -> Bool) -> phi ix -> f r ix -> f r ix -> Bool

Instances

HEq phi U

Eq a => HEq phi (K a)

For constant types, we make use of the standard equality function.

El phi xi => HEq phi (I xi)

(Constructor c, HEq phi f) => HEq phi (C c f)

HEq phi f => HEq phi (:>: f ix)

(Eq1 f, HEq phi g) => HEq phi (:.: f g)

(HEq phi f, HEq phi g) => HEq phi (:*: f g)

(HEq phi f, HEq phi g) => HEq phi (:+: f g)

class Eq1 f where

Methods

eq1 :: (a -> a -> Bool) -> f a -> f a -> Bool

Instances

Eq1 []

Eq1 Maybe

eq :: (Fam phi, HEq phi (PF phi)) => phi ix -> ix -> ix -> Bool
