Avoiding memory leaks with Scalaz 7 zipWithIndex/group enumeratees

January 2, 2023 by Tarik

This will come as little consolation for anyone who’s stuck with the older iteratee API, but I recently verified that an equivalent test passes against the scalaz-stream API. This is a newer stream processing API that is intended to replace iteratee. For completeness, here’s the test code: // create a stream containing `n` arrays with … Read more

Scalaz iteratees: “Lifting” `EnumeratorT` to match `IterateeT` for a “bigger” monad

September 17, 2022 by Tarik

In the usual encoding an enumerator is essentially a StepT[E, F, ?] ~> F[StepT[E, F, ?]]. If you try to write a generic method converting this type into a Step[E, G, ?] ~> G[Step[E, G, ?]] given an F ~> G, you’ll quickly run into an issue: you need to “lower” a Step[E, G, A] … Read more
