Thanks, the idea was to use Rust also to learn it but based on the description the idea used there is the same or very similar to what I’ve implemented - so maybe there are some interesting way to improve and optimize what I got.

Hah, well that’s an interesting coincidence then. May I ask what is your general idea on the subject? How do you structure them and “train” them? As my assumption is that “training”/learning/etc. requires some form of feedback loop - where the result of the current inference/calculation must (or may) impact the calculation of the next one, in my solution this is done by adding the memory part.
