Trying to figure out web_sys::AudioWorkletProcessor

Summary

I'd like to create and register an AudioWorkletProcessor using Rust. I'm still not sure if it's possible.

Additional Details

I've also put up a question on StackOverflow.

I'm currently stuck on having to extend AudioWorkletProcessor for the sake of overriding the process() function. And I'm also not yet sure if it's going to be possible to access AudioWorkletGlobalScope. On top of all this, I have no idea if it will play well with webpack / or any other bundler. This is what I've got so far:

use wasm_bindgen::prelude::*;
use web_sys::{ AudioWorkletGlobalScope };

#[wasm_bindgen]
pub fn create_worklet_node() {
  AudioWorkletGlobalScope::register_processor(/* MISSING ARGUMENTS */);
}

#[wasm_bindgen]
extern "C" {
  #[wasm_bindgen(extends = web_sys::AudioWorkletProcessor)]
  type MyAudioWorkletProcessor;
}

#[wasm_bindgen]
impl MyAudioWorkletProcessor {
  pub fn process() {
    // this would throw an error if I was doing it right... :/ 
  }
}

Potential Incentive

I think that multi-threaded audio processing is an extremely good example of the power of wasm, so I'd probably not be the only person who could really use an example of how to set up an AudioWorklet using Rust.

Thanks for this project!
