   # rcl_logging_noop
   
   Package supporting an implementation of no-op logging functionality.
   
   [rcl_logging_noop](src/rcl_logging_noop.cpp) logging interface implementation can:
    - initialize
    - log a message
    - set the logger level
    - shutdown
   
   ## Build
   
   Currently there is no way to select the logging interface implementation without building [rcl](https://github.com/ros2/rcl) with target logging interface implementation.
   
   ```bash
   export RCL_LOGGING_IMPLEMENTATION=rcl_logging_noop
   colcon build --symlink-install --cmake-clean-cache --packages-select rcl_logging_noop rcl
   ```
