either make something that works for Applicative so it works for both and any other implementation; or make 2 functions, one for either and the other for validated

[Gopal S Akshintala]

Thanks @pakoito, since bimap is common for both Either and Validated, my intention is to write one function for it. How can I achieve this with Applicative?

[pakoito]

Bifunctor then

[Gopal S Akshintala]

Hmm, let me explore

[Gopal S Akshintala]

This is what I did

```

[Gopal S Akshintala]

fun <S> User.upsert(BF: Bifunctor<S>, result: Kind2<S, Nel<ValidationError>, Unit>) =
            BF.run {
                result.bimap(toLeft(), toRight())
            }

[Gopal S Akshintala]

Calling it this way: user.upsert(Either.bifunctor(), result)

[Gopal S Akshintala]

But there is no bifunctor() for Validated 😞

@pakoito

[raulraja]

BiFunctor should be possible in Validated, if you want to contribute it to the validated instances we could include it in the next release

[raulraja]

should look fairly similar to the Either instance

[Gopal S Akshintala]

Sure, I shall do that 🙂

[Gopal S Akshintala]

@raulraja Just FYI, My PR for Validated Bifunctor got merged last Friday

[raulraja]

congrats!
