Is there a cross platform AutoCloseable Iterable solution for Scala?

I am porting a library banana-rdf to Scala3. The library aims to provide a no-cost efficient interface for RDF libraries written in Scala, JS (and hopefully even native at some point).

I am currently working on the implementation for the Jena library that returns AutoCloseable iterators, which made me wonder how I should best deal with those.

  • If I convert that type to an scala Iterable then I loose the closeable interface on it, losing the information that the caller should make sure to close it before using it;
  • I looked at scala.util.Using, but that requires the resource to be iterated through, which is something for the calling code to determine, not the library;
  • should one just return the Java iterator? But I would need to check if that plays well with ScalaJS code
  • Other ideas?
scala.js scala-3 scala

One could use the Java Iterable and Closeable interfaces, and build on that.
