Module connection 

Low-level single-connection driver.

This module manages a single MQTT connection: transport setup, CONNECT / CONNACK handshake, the packet read/write loop, keep-alive, and pending-ack tracking. It is an internal implementation detail of the crate; the public API is provided by MqttClient.
