Output function name based on constant string

Actually, I probably want to generate some code for my client based on my Rescript function files.

On the server side I have something like:

let createOrder: Firebase.Functions.callableFunction<
  Domain.createOrderRequest,
  string,
> = Firebase.Functions.Https.onCall(
  ~opts={
    region: Domain.firebaseRegion,
    allowedCors: Common.allowedCors,
  },
  ~handler=request => {
    let requestData: createOrderRequest = request.data
    Console.log(requestData)
    Promise.resolve("https://nojaf.com")
  },
)

If I can somehow process all files and detect any let binding that has type callableFunction and generate my client side API.

Something like:

let createOrder: Firebase.Functions.httpsCallable<
  Domain.createOrderRequest,
  string,
> = Functions.httpsCallable(functions, ~name="createOrder")

if I can generate this, it will always match my server code.

Is there any way to get the ReScript (typed) AST?
