Task

Unlike scala.concurrent.Task, this Task is not memoized by default.

var count = 0
val notMemoized = Task.delay {
  count += 1
}
count should be(0);
(
  for {
    _ <- notMemoized
    _ = count should be(1)
    _ <- notMemoized
    _ = count should be(2)
    _ <- notMemoized
  } yield (count should be(3))
).toFuture

A Task can be memoized manually by converting this Task to a scala.concurrent.Task and then converting back.

var count = 0
val notMemoized = Task.delay {
  count += 1
}
val memoized = notMemoized.toFuture.toTask;
(
  for {
    _ <- memoized
    _ = count should be(1)
    _ <- memoized
    _ = count should be(1)
    _ <- memoized
  } yield (count should be(1))
).toFuture
