Anyone want to volunteer a guide for when to use #yoneda instead of #coyoneda in #haskell or #purescript ?

I'm wanting to provide an HFunctor (https://pursuit.purescript.org/packages/purescript-fix-functor/0.1.0/docs/FixFunctor#t:HFunctor) instance but the naive way to do that requires me to "invent" a Functor instance for the source type constructor -- thinking of adding a yoneda/coyoneda wrapper and I think either would work, but I'm not sure.
