How to call js function in rust and pass argument to it?

[taikulawo]

We are embedding deno into rust do some http filter mechanism , it's more like nginx-njs project

In order call deno, we need collect the exported js function and store on rust side. When http request comes, we call js and pass some http context to it(http request and http response object) with method on it.

There are two questions.

1. how to collect js function on rust side?
2. how to pass arguments when calling?
