How to assign a function object to property of the napi object?

[yuchanns]

A javascript object can be assigned with a function object as its property like:

let extendableObj = { name: "example", extendsPlugin: (p) => { p.use(somePlugin) } }

How to do when it comes to napi object?

Try:

#[napi(object)]
pub struct ExtendableObj {
    pub name: &'static str,
    pub extends_plugin: Box<dyn Fn()>,
}

Not work as the trait bound Box<dyn Fn()>: NapiRaw is not satisfied, neither to fn().

Box<dyn Fn> is not supported to create from JavaScript function, use JsFunction instead
