Mosquitto plugins written in rust, help with contents of mosquitto struct [message #1835452]

Mosquitto broker is a mature and simple, and quite frankly defactor standard MQTT broker in use today.

However I do not enjoy writing stuff in C to much, so I created a library that will help aspiring plugin writers to write their plugin in rust, and use it in Mosquitto broker. Will post links in next message

Repository with example: https://github.com/TotalKrill/mosquitto_plugin

I have included an example plugin that only let clients connect if their password is their username in reverse, and also only allows subscribtion/publish depending on their mosquitto.conf file. You will find it in the repository.

I would however want some help, the mosquitto_plugin.h header file doesnt specify the mosquitto struct. So I have not been able to incorporate information from that struct into my plugin library yet.

Any help is appreciated!

Great, good work!

`struct mosquitto` is private, and will remain so forever. You can use the accessor functions in `mosquitto_broker.h` to get access to some parameters, are there any other parameters that you are missing?
