Detailed Description

These logging levels follow the Python Standard https://docs.python.org/3/library/logging.html#logging-levels And are implemented in rcutils as well https://github.com/ros2/rcutils/blob/35f29850064e0c33a4063cbc947ebbfeada11dba/include/rcutils/logging.h#L164-L172 This leaves space for other standard logging levels to be inserted in the middle in the future, as well as custom user defined levels. Since there are several other logging enumeration standard for different implementations, other logging implementations may need to provide level mappings to match their internal implementations.

LogPublisher publishes log values to a ROS 2 topic. Set the topic and node properties, then call publish() to send messages.

See also LogSubscriber and log.
