D中的单线程将来/承诺？

问题描述

我看到D有期货，并且可以创建线程，但是是否有类似 Dart的期货/承诺（或者，如果您使用的是库，我猜是JavaScript）吗？

I see that D has futures, and can create threads but is there anything like "Dart" futures/promises (or I guess javascript if you use a library)?

我希望能够编写这样的代码-

I want to be able to write code like this -

//
// NOT D code because I can't remember all the syntax!
//
auto fut = myfile.read();

fut.then(function(data) {
    // Process data asynchronously when the future completes
};

我希望在与主代码相同的线程上进行回调。这大概需要某种均匀的队列和事件分派。
我认为ASIO在boost中提供了一些类似的C ++功能，但是语法更好的东西会很好。

I want the callback on the same thread as the main code though. This will presumably need some kind of even queue and event dispatching.I think that ASIO in boost provides some similar facilities for C++ but something with a better syntax would be nice.

核心D中是否有类似的东西，或者有任何简单的方法来实现单线程

Is there anything like this in core D, or any simple way to achieve single threaded futures for async code?

推荐答案

我建议您看一下vibe.d：
它使您可以编写高性能的事件驱动代码，就像从nodejs所知道的那样，但是可以使用D的光纤以同步的方式进行：

I suggest you take a look at vibe.d: http://vibed.org/It enables you to write performant event driven code like you know from nodejs but in a synchronous manner using D's fibers: http://dlang.org/phobos/core_thread.html#.Fiber
