In modern C++ development, coroutines have brought revolutionary changes to asynchronous programming. However, when using boost::asio or standalone asio, we often encounter scenarios where we need to convert traditional std::future
Problem Background
When using asio coroutines, we often encounter scenarios like:
Need to call third-party libraries that return std::future (such as database drivers)
(such as database drivers) Want to use co_await in coroutines to handle these asynchronous operations
in coroutines to handle these asynchronous operations Don’t want to block IO threads, maintaining high performance
Traditional solutions might use timer polling or directly call future.get() in IO threads, but these methods are either inefficient or block IO threads.
Core Solution
Our solution is based on asio::async_initiate , which provides perfect integration with the asio coroutine system while avoiding the problem of blocking IO threads.
