I have a database DAO from which I want to return a

Sequence

. However, I also want to close the db cursor when the sequence has finished consuming. Is this a valid approach?

suspend fun findSomethings(...): Sequence<Something> {
  val cursor = ...
  return sequence {
    cursor.use {
      yieldAll(cursor.iterator())
    }
  }
}

I would not use that approach. Mainly because if the user of the returned

Sequence

does not fully iterate through it, your cursor will not be closed.
