Module mqtt.connector
Auto detect the connector to use.
The different environments require different socket implementations to work properly. The 'connectors' are an abstraction to facilitate that without having to modify the client itself.
This module is will auto-detect the environment and return the proper module from;
* mqtt.connector.nginx for using the non-blocking OpenResty co-socket apis
* mqtt.connector.copas for the non-blocking Copas wrapped sockets
* mqtt.connector.luasocket for LuaSocket based sockets (blocking)
Since the selection is based on a.o. packages loaded, make sure that in case
of using the copas scheduler, you require it before the mqtt modules.
Since the client defaults to this module (mqtt.connector) there typically is no need to use this directly. When implementing your own connectors, the included connectors provide good examples of what to look out for.
