Здравствуйте, подскажите, как сделать мои корутины и awaitable объекты совместимыми

с корутинами в boost asio ?

Возможно, чтобы твой классец можно было поюзать со следущим кодом ''' #include <boost/asio/io_context.hpp> #include <boost/asio/co_spawn.hpp> #include <boost/asio/use_awaitable.hpp> int main() { asio::io_context ioContext; asio::co_spawn(ioContext, []() -> asio::awaitable<void> { YourClassName your_class_instance; auto result = co_await your_class_instance; for (const auto& smth : result) { std::cout << smth << std::endl; } }, asio::use_awaitable); ioContext.run(); return 0; } ''' твой класс должен реализовывать два метода: auto await_suspend(std::coroutine_handle<> handle) void await_resume() {} А так же версия буста должа быть совместима с std::coroutine_handle<> (с++20) Но что конкретно ты подразумеваешь под своими корутинами... и с чем они у тебя без примера mre совместимы

Сейчас кину mre

Мой класс такое реализует, но с корутинами boost::asio он не работает

Это не boost::asio, это boost::coroutine2

Я про boost::asio::awaitable

Аминь

В Godbolt.org/z/hx1nvKafE есть буст 1_83й Посмотри командную строку И дополни своим mre

^ го!
