rate.sleep()
does return false
in that case, so it would be possible to listen for that and sleep manually then. But the purpose of returning false
seems to be for backwards jumps in time, so I don't know if that is a reliable way of circumventing the problem.

I think this is ill-conditioned requirement.

For what amount of time would you like to sleep? If using simulation time, imagine /clock
has simulation times sequence 0, 10, 20, 30... Now, what should a Rate(1).sleep()
do? The time is 10, the sleep is called, what now? If the call would be blocking, you would not get rate higher than the simulation clock.
I think the expected behavior is that the 1st to 9th sleeps are non-blocking and the 10th sleep is blocking. Is that right?
I think in your specific case, you either have to increase resolution of the simulation clock or rewrite the logic of the rate loops. I think a token-bucket rate limiter could work. One such implementation is in http://docs.ros.org/en/melodic/api/cras_cpp_common/html/classcras_1_1TokenBucketLimiter.html .
