Minimal “subscriber” cookbook recipes
This package contains a few different strategies for creating short nodes that display received messages.
The subscriber_old_school
recipe creates a listener node very similar to how it would be done in ROS 1 using rospy.
The subscriber_lambda
recipe shows how to embed the callback functions inside your main.
The subscriber_member_function
recipe creates a class MinimalSubscriber that contains the callback, keeping the main simple.
