Use external event loop

[bkanuka]

Some changes have been made to Paho MQTT to (actually) allow the use of an external event loop. See Issue 72 - which I beleive actually references this project. It may also be helpful to see the example usage of asyncio.

You may want to have a look at asyncio-mqtt: https://github.com/sbtinstruments/asyncio-mqtt

It wraps paho-mqtt in an idiomatic asyncio-based interface. Underneath, it uses the mechanisms described eclipse-paho/paho.mqtt.python/issues/72.

Full disclosure: I'm the author of asyncio-mqtt

Good stuff! I wrote a similar library for trio (not vanilla async like you did) but forgot to "advertise" it. Here's mine: https://github.com/bkanuka/trio-paho-mqtt

Hello all, sorry I've not got back to any of you about using the event loop properly and for your very helpful references. (A combination of having children and the pandemic have been a bit of a hindrance!)

Given the existence of these very nice asyncio MQTT libraries, it seems to me the best thing to do is recommend passers by towards asyncio-mqtt (cracking job, @frederikaalund -- this is the library I'd have wished I'd had when I cobbled this one together!).

Whilst I intend to keep this library alive at least (some things I use depend on it) the current inelegance of its construction is not a big enough motivator to change things for now so I'll leave this issue here to track that fact.
