Python bindings

Hopefully with this it will make it easier to integrate into the add-on.

Requires Maturin.
Allows you to call train from python as shown in py/test.py.

Run

make test

Or manually create a .venv and run maturin develop

Should run as if it was called from rust

If we integrate FSRS into Anki client, should we still need to integrate the training module into the add-on?

I'm afraid I don't think this PR is a good idea.

• This repo is less than a week old, and the API is still in flux.
• You've added a requirement on Python. If Anki is to be able to integrate this in the future, the crate needs to be importable by Anki's Rust library, which should work without Python.
• The plan is to expose training in a way that the UI can show. The current training method requires a console to show progress, which most Anki users will not have.

I would recommend waiting until the API gets decided on, and this gets integrated into Anki's Rust library - then users will be able to access it directly and will not even need an add-on. If you did still want to expose it separately in Python for some reason, once the API is determined, you could do so by creating a separate Rust crate that exposes this crate's public API, like how Anki has a normal Rust crate and a separate pyo3 crate.

Oh are we integrating it into Anki itself? I'd always assumed the add-on was the goal.
This could be integrated into the add-on but if its going to be integrated into Anki itself where the native rust code can call it I agree there's little point to this.

I quickly added it into the addon as a proof of concept.
It does work but:

• is still limited to the command line progress bar
• would need different builds for different os's
• Anki hangs when its running.

If you want to test it clone it recursively then run make.

Again if this is going to be added into anki there isnt much point in this.

Yep, the plan is to integrate this crate in Anki.

Sounds great to me 👍.
