Mapping a failure to success

[badvok666]

This is probably not an issue. Its more of a query i have. I very well could be misusing, misunderstanding or not aware of something.

The use case is if the api call fails i want it to successfully return the cache.

Much like andThen allows the transforming of one thing to another contained withing the Result type. What i feel i am looking for is a way to "andThen the error". So i can transform the E into a success using Ok(SomeType)

I can't find the function though i could just be using it wrong/this is not the correct practice.
For now i'm letting my Error contain any type so it can optionally return the result i want.

Thanks in advance, really loving using kotlin-result so far.

I think you want recover

It would go something like:

class Good( ... )
class Bad(... )

fun makeCall() : Result<Good, Bad> = { ... }

fun caller() {
   val result: Ok<Good> = makeCall().recover { error -> Good(...)  }
}

I think that it is.

Thanks!!, Totally loving this and am in the process of replacing sealed classes. I do not miss the in-lining of the when()s
