Struct MqttTopicSubscriber

Source 
pub struct MqttTopicSubscriber<MessageType, PayloadType, SerializerType> { /* private fields */ }
Expand description

Structured MQTT subscriber with automatic topic parameter extraction.

Created via #[mqtt_topic] macro. Converts raw MQTT messages into structured types.
