    Spin! Day and Night

    This means ros::spin and ros::spinOnce will not call these callbacks. Instead, you must service that queue separately. Some examples include: Long-running services.

    Apr 05,  · spin_once() is typically used to integrate with another thing that needs the same thread (like if ROS and Qt need the main thread, they can take turns "spinning" to share the time), but can be used to do what you're doing. A better way to do this (in my opinion) would be to use a future and store the data in it and complete the future when the data set is completed, that way you can use. Unlike its std equivalent, this is generalized so that The closure returns a value and it is stored. Once therefore acts something like 1a future, too. Examples #! [feature (const_fn)] use spin; static START: spin:: Once = spin:: Once:: new (); START. call_once (|| { // run initialization here});.

    Assigning a service its own callback queue that gets serviced in a separate thread means that service is guaranteed not to block other callbacks. Threading specific computationally expensive callbacks. Similar to the long-running service case, this allows you to thread specific callbacks while spij the simplicity of single-threaded callbacks for the rest your application.

    This method is typically called in a loop and may change in behavior based on the number of times SpinOnce has been called so far on oncr instance. Each spin results in the SpinWait method being called. A count is kept of the number of times SpinOnce is called, and after a threshold count is reached, the Yield method is called.

      I can't figure out which is the correct way of using rclpy. Right now I'm using a simple while that loops until all callbacks have new values.

    2. Tina Henderson:

      Check out the ROS 2 Documentation. This means that while roscpp may use threads behind the scenes to do network management, scheduling etc. The end result is that without a little bit of work from the user your subscription, service and other callbacks will never be called.
