Cats EitherT convert to Future[Result]

Question

I have result like:

EitherT[Future, IllegalStateException, Result]

how to convert to Future[Result]? And let Future fail with this IllegalStateException? I know I can do like resultT.value to get Future[Either[Exception, Res]] and convert it but maybe there is simpler way.

Answer 1

There isn't really any simpler version to do it than what you've mentioned. But the conversion isn't hard to do either, so there isn't really a need.

import scala.util.chaining._
resultT.value.flatMap(_.toTry.pipe(Future.fromTry))

Answer 2

As I always say, the Scaladoc is your friend.

All you need to do is:

resultT.rethrowT
