Bifunctors
Branch: CURRENT,
Version: 5.5.6,
Package name: hsbifunctors5.5.6,
Maintainer: szptvlfnA bifunctor is a type constructor that takes two type arguments and is
a functor in both arguments. That is, unlike with Functor, a type
constructor such as Either does not need to be partially applied for a
Bifunctor instance, and the methods in this class permit mapping
functions over the Left value or the Right value, or both at the same
time.
Formally, the class Bifunctor represents a bifunctor from Hask >
Hask.
Intuitively it is a bifunctor where both the first and second
arguments are covariant.
You can define a Bifunctor by either defining bimap or by defining
both first and second.
