Is it possible and recommended to create custom handlers for boost::asio? Are there tutorials on how to do it? After searching for quite some time for it I didn't find anything (only custom allocators in boost::asio).
asio currently supports to provide callbacks, using use_awaitable, use_future for std::futures and more. I would like to have an implementation which works with a boost::future or another kind of future (like the one from stlab) rather than a std::future. Of course, I could study the boost source code and try to mimic it, but that seems rather cumbersome with all the portability details.
