How to support asynchronous processing in JsFn::call ?

[gudaoxuri]

Hi,

I want to call rust's asynchronous processing logic in js (such as hyper_wasi project's asynchronous httpclient), how should I handle it?

struct HttpGetFn;
impl JsFn for HttpGetFn {
    fn call(ctx: &mut Context, _this_val: JsValue, argv: &[JsValue]) -> JsValue {
        // How to support asynchronous processing? like:
        // let resp = http_req(...).await;
    }
}
