> I'm trying to write a simple ASIO send/receiver that uses message queueing. The goal is to have a number of virtual streams over a single TCP connection.  This is pretty simple using callbacks, but I can't figure out the coroutines alternative. Here is my simplified sample code. Note that I'm using asio::experimental::promise the same way I would use std::promise which obviously doesn't work, but it illustrates what I'm trying to do. What is the simplest solution to my problem?

Have you considered utilizing asio::experimental::basic_channel?

By the way, there is no synchronization mechanism in Asio akin to a
future/promise pair, if you're open to external solutions, you might
want to explore these options:
