将列表[任务[布尔]]转换为EitherT [任务，可投掷，单位]

Question

I have a List[Task[Boolean]] and I need to turn it into an EitherT[Task, Throwable, Unit] .

I have one possible solution which is

EitherT(Task.delay(if (!allAsserts.contains(false)) \/-(()) else -\/(new Exception("BOOM"))))

but I was wondering if it's possible to create the EitherT without making an explicit call to Task.delay .

Perhaps the above code is correct but I was just wondering if there are alternatives.

Answer 1

Perhaps this?

lazy val toDisjuction: List[Boolean] => \/[Throwable, Unit] = list =>
  if (list.forall(_ == true)) \/-(()) else -\/(new Exception("BOOM"))

val ltb: List[Task[Boolean]] = ???

EitherT(Task.gatherUnordered(ltb) map toDisjunction)

I think that's what I was looking for ...
