Return functions

[Phara0h]

Any way to do this

addon.foo((string)=>{
  string = "slkdfjsf";
  return string;
})

or this

addon.foo((func)=>{
  func("slkdfjsf")
})

not yet, is something you need?

[Phara0h]

Yes this would be needed for porting over a http framework im working on.

This is what im looking to write.

request.get('/test/:foo', (req, res)=>{
  
  res({
     status:200,
    body: 'hello'
  })
// or this

res.send('hello');
})

Hmm, in this case rust fn would something like this:

struct Response {
....
}

struct Request {
....
}

impl Request {
    #[node_bindgen]
    async fn get<F,T,R>(path: String, handler: F)
          where F: FnOnce<Req,Response> -> T,
                 T: Future<Output = Response> + 'static + Send
{
          let req = // create req 
          let resp = // create response
          let response = handler(req,resp).await;      // wait JS to return invoke response
          
          ...do something with response, probably return to client
    }
}

Tricky part is how to map Response which is actually function call from JS point of view.

It would be be easier instead of callback, pass async fn.
