Looking for a Proxy implementation similar to quickjs_runtime

[BharathIO]

Summary

I have implemented a JS proxy using quickjs_runtime where i have my own custom classes and methods implemented in rust and can be callable from javascript methods.

https://github.com/HiRoFa/quickjs_es_runtime

Ex: I have

Javscript code

class PdfDocument {

}

this.doc = new io.pdf.PdfDocument(__id__, docProps);

io.pdf.PdfDocument is a proxy and implemenation in rust using JsProxy of quickjs_runtime.

Rust code

 let proxy = JsProxy::new()
                .namespace(&["io", "pdf"])
                .name("PdfDocument")

Is there any similar way to implement python as well?

Ex: Implementaion should be completely in rust where as calling is from Python.
