1.从runtime::Builder::new_multi_thread开始 第二个运行时由Session拥有,它在asynchronous测试结束时被删除。您可以通过使用mem::forget跳过析构函数来观察这一点:尝试:cargo run --release而不是cargo runhttps://dev.to/scyart/comment/1f88p

This is not an async function. It will do its work synchronously, and return once everything is set up. First we're going to create our Arc<Mutex<...>> bit and make a clone of it for a callback function: let waker = Arc::new(Mutex::new((0, None))); let waker_clone = ...

The first message is pretty direct: you can only use the.awaitsyntax inside anasyncfunction or block. We haven't seen anasyncblock yet, but it's exactly what it sounds like: async {// async noises intensify} The second error message is a result of the first: theasynckeyword causes the...
