Конфигурация cmp_mqtt_client

Fields§

§client_id: String

Идентификатор клиента MQTT

§host: String

§fn_input: ConfigFnInput<TMsg>

Функция преобразования входящих сообщений в данные для публикации в брокере

Примеры

  • ничего не отправлять в брокер
fn_input: |_| Ok(None)
  • сериализация данных без фильтрации
fn_input: |msg| Ok(Some(msg.serialize()?.into_bytes()))

fn_output: |_| Ok(None)
  • десериализация данных без фильтрации
fn_output: |payload: &[u8]| {
    let payload = String::from_utf8_lossy(&payload);
    let msg = Message::deserialize(&payload)?;
    Ok(Some(msg))
}
