Exposing functions/classes from Java (using a WASM runtime) to RustPython

[Yu-Vitaqua-fer-Chronos]

Heya, the title says it all haha, I'm interested in trying to embed RustPython into my Java application, and I want to use it as a scripting language, but I don't know how I'd expose a function to it at all really, is there anything specific I'd need to do? Any advice to use this within Java too? GraalVM would be ideal but as that isn't an option for me, I'd like to look at other ways of doing this

wow, interesting challenge.

This is including 3 separated parts.

1. exporting java symbol to wasm side. I think you will handle this well.
2. importing wasm symbol to rust. I don't know well about wasm, but wasm_bindgen is the part rust recognize wasm symbols in rust.
3. RustPython recognize wasm symbols as Python function. I think this is manually approachable like wasm/lib/src/js_module.rs, but not sure how to do exactly.

@coolreader18 any advice?

I've actually seen a few projects such as "New Moon With Report" that give this functionality, I just don't know if it'll run with RustPython haha, something to test when i can
