1. newtype Product a

   base-compat-batteries	Data.Semigroup.Compat

   Monoid under multiplication.

   Product x <> Product y == Product (x * y)
   

   Examples

   >>> Product 3 <> Product 4 <> mempty
   Product {getProduct = 12}
   

   >>> mconcat [ Product n | n <- [2 .. 10]]
   Product {getProduct = 3628800}
   

2. Product :: a -> Product a

   base-compat-batteries	Data.Semigroup.Compat

   No documentation available.

3. type Prism s t a b = forall (p :: Type -> Type -> Type) (f :: Type -> Type) . (Choice p, Applicative f) => p a f b -> p s f t

   generic-lens	Data.Generics.Internal.VL

   Type alias for prism

4. type Prism' s a = Prism s s a a

   generic-lens	Data.Generics.Internal.VL

   No documentation available.

5. module Data.Generics.Product

   Magic product operations using Generics These classes need not be instantiated manually, as GHC can automatically prove valid instances via Generics. Only the Generic class needs to be derived (see examples).

6. module Data.Generics.Product.Param

   Derive traversals over type parameters

7. data family Param :: Nat -> j -> k

   generic-lens	Data.Generics.Product.Param

   No documentation available.

8. module Data.Generics.Product.Positions

   Derive positional product type getters and setters generically.

9. type family Prec' w

   generic-random	Generic.Random.Internal.Generic

   No documentation available.

10. type PixbufDestroyNotify = Ptr Word8 -> IO ()

    gi-gdkpixbuf	GI.GdkPixbuf.Callbacks

    A function of this type is responsible for freeing the pixel array of a pixbuf. The pixbufNewFromData function lets you pass in a pre-allocated pixel array so that a pixbuf can be created from it; in this case you will need to pass in a function of type GdkPixbufDestroyNotify so that the pixel data can be freed when the pixbuf is finalized.
