Boost asio C++ 20 Coroutines: co_spawn是一个具有引用参数意外结果的协同线。 、、、 在下面的代码中,会话协同线的参数通过引用传递。session(const std::string& name) std::cout << "Starting " << name << std::endl; auto executor = co_await> g++ -std=c++20 ../test-coro.cpp -o ...
“We have a functiondoSomeWorkwhich is defined as a coroutine. It usesco_returnto return the result of an expression that is awaited usingco_await. This allows the Qt6 application to run the time-consuming operation asynchronously.”(我们有一个名为doSomeWork的函数,它被定义为一个协程。这个函...

我正在涉足关于 boost::asio 的协程,并且我对异常处理感到困惑。从文档中的示例来看,看起来任何“失败”都会变成异常 - 所以我希望假设抛出的任何异常也会传播回调用。但情况似乎并非如此:error_codeco_spawn #defineBOOST_ASIO_HAS_CO_AWAIT#defineBOOST_ASIO_HAS_STD_COROUTINE#include<iostream>#include<boost/asio...
也就是 asio 作者所说的 co_spawn. 只有被 spawn 出来的协程,才叫一个任务。而被 await 的函数,不能叫任务,而是”可异步等待返回的函数“。 因此 asio 作者使用 asio::awaitable<> 来命名,而不是 task<> 是十分妥帖的。接着是 promise_type ,这个微软就是纯粹的瞎搞了。不同于 Task<> 只是出现在微软...

Using async_launch_scope the parent coroutine can use scope.spawn(awaitable) to start the client coroutines and keep track of them. Once the server receives a shutdown signal it can use the awaitable returned from scope.join() to wait until all of them have finished. This is similar to...
协同等待co_spawn后ASIO链被阻塞(_A)是一种涉及到协程和异步网络编程的概念。 协程是一种轻量级的线程,可以在同一个线程中实现多个任务的并发执行。ASIO(Asynchronous I/O,异步I/O)是一种基于事件驱动的网络编程库,常用于开发高性能的网络应用。 在协程编程中,co_spawn是一种用于创建协程的函数。当使用co_spawn...
