Example use of tink.core.Future in UFront controllers

AsyncTestController.hx

import tink.core.Error;
import tink.core.Future;
import tink.core.Outcome;
import ufront.web.result.ContentResult;

class AsyncTestController extends  ufront.web.Controller {

	@:route('/async') public function async() return simulatedAsyncProcess();
	
	function simulatedAsyncProcess(): Surprise<ContentResult, Error> {
		var f = Future.trigger();		
		
		// simulated async processing...
		#if (neko) Sys.sleep(1); #end 
		if (Random.bool()) 
			f.trigger(Success(new ContentResult('This is the result from a simulated async success! :-)')));	
		else 
			f.trigger(Failure(new Error('This is a simulated async error - happens every second time...')));

		return f.asFuture();
