Detailed Description

This file defines the event topics and messages used throughout the Uniot MQTT subsystem. These events enable communication between MQTT clients, connection managers, and other system components that need to respond to MQTT connectivity changes.

The event system uses FOURCC (Four Character Code) identifiers for efficient event routing and minimal memory footprint. MQTT events are organized into:

• Topics: Event categories (e.g., connection events)
• Messages: Specific event types within topics (e.g., success, failure)

Example usage:

// Emit an MQTT connection success event
eventEmitter.emitEvent(events::mqtt::Topic::CONNECTION,
                      events::mqtt::Msg::SUCCESS);
 
// Listen for MQTT connection events
eventListener.listenToEvent(events::mqtt::Topic::CONNECTION);
