Web Component with CustomElementRegistry

[kczimm]

Summary

I want to make a Web Component. How do I define my custom Web Component in the CustomElementRegistry? Specifically, how do I pass the constructor as a &js_sys::Function?

Additional Details

#[wasm_bindgen]
pub struct WebComponent;

#[wasm_bindgen]
impl WebComponent{
    #[wasm_bindgen(constructor)]
    pub fn new() -> Self {
        todo!()
    }
}

#[wasm_bindgen(start)]
pub fn main() {
    let window = web_sys::window().unwrap();
    window
        .custom_elements()
        .define("web-component", ?) // how do I get a &js_sys::Function from WebComponent::new?
        .unwrap();
}
