1. invmapFunctor :: Functor f => (a -> b) -> (b -> a) -> f a -> f b

   invariant	Data.Functor.Invariant

   Every Functor is also an Invariant functor.

2. invmapProfunctor :: Profunctor p => (a -> b) -> (b -> a) -> p a a -> p b b

   invariant	Data.Functor.Invariant

   A Profunctor with the same input and output types can be seen as an Invariant functor.

3. makeInvmap :: Name -> Q Exp

   invariant	Data.Functor.Invariant.TH

   Generates a lambda expression which behaves like invmap (without requiring an Invariant instance).

4. makeInvmap2 :: Name -> Q Exp

   invariant	Data.Functor.Invariant.TH

   Generates a lambda expression which behaves like invmap2 (without requiring an Invariant2 instance).

5. makeInvmap2Options :: Options -> Name -> Q Exp

   invariant	Data.Functor.Invariant.TH

   Like makeInvmap2, but takes an Options argument.

6. makeInvmapOptions :: Options -> Name -> Q Exp

   invariant	Data.Functor.Invariant.TH

   Like makeInvmap, but takes an Options argument.

   No documentation available.

10. sFmap :: forall a b (t1 :: a ~> b) (t2 :: f a) . SFunctor f => Sing t1 -> Sing t2 -> Sing (Apply (Apply (FmapSym0 :: TyFun (a ~> b) (f a ~> f b) -> Type) t1) t2)

    singletons-base	Control.Monad.Singletons

    No documentation available.
