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.

log is a structured value type usable in QML. It maps directly to the rcl_interfaces::msg::Log ROS 2 message type.

Construct a log in QML by assigning a JavaScript object whose keys are its component properties, or by setting those properties individually.
