copper VS mosquitto_transport

I have been reading the documents from Boost.fibre and Boost.Signals2 which I could use, maybe ASIO for async. I also checked ZeroMQ (this seems to be more or less "only" for networking), Copper and Rotor. If this were just a simple MCU project I would just take the FreeRTOS and would have everything I need. Now I'm just lost how to structure my code / how to realize my main loop.

In the meantime, are you aware of any projects that are similar? Have you come across copper? It looks nicely designed - is this the kind of thing you imagine would be similar?

You might be interested in having a look at my recent library with a similar goal: https://github.com/atollk/copper

Looking at the reference docs, and just wow. This is a very well documented project, great work!

mosquitto_transport, an experiment of writing SObjectizer-based wrapper around mosquitto library;

PS. Five years ago we used MQTT+SObjectizer in one of our projects, a part of it is available as [mosquitto_transport](https://github.com/Stiffstream/mosquitto_transport). You can take a look at it and get an idea of how MQTT and SObjectizer can be integrated together (maybe it's not a best way, but that approach worked well for us).
