Functions
double	cras::frequency (const ::ros::Rate &rate, bool maxCycleTimeMeansZero=false)
	Return the frequency represented by the given rate. More...
double	cras::frequency (const ::ros::WallRate &rate, bool maxCycleTimeMeansZero=false)
	Return the frequency represented by the given rate. More...
::ros::Time	cras::nowFallbackToWall ()
	Return current ROS time if it has already been initialized, or current wall time. More...
::ros::Duration	ros::operator* (const ::ros::Duration &val1, const ::ros::Duration &val2)
	Multiply two durations. The units of the result are [s^2]. More...
::ros::WallDuration	ros::operator* (const ::ros::WallDuration &val1, const ::ros::WallDuration &val2)
	Multiply two durations. The units of the result are [s^2]. More...
::ros::Duration	ros::operator/ (const ::ros::Duration &numerator, const ::ros::Duration &denominator)
	Divide duration val1 by val2. The result is unitless. More...
::ros::WallDuration	ros::operator/ (const ::ros::WallDuration &numerator, const ::ros::WallDuration &denominator)
	Divide duration val1 by val2. The result is unitless. More...
bool	ros::operator== (const ::ros::Rate &r1, const ::ros::Rate &r2)
	Test two rates for equality. More...
bool	ros::operator== (const ::ros::WallRate &r1, const ::ros::WallRate &r2)
	Test two rates for equality. More...
::ros::Duration	cras::remainingTime (const ::ros::Time &query, double timeout)
	Return remaining time to timeout from the query time. More...
::ros::Duration	cras::remainingTime (const ::ros::Time &query, const ::ros::Duration &timeout)
	Return remaining time to timeout from the query time. More...
::ros::Rate	cras::safeRate (double frequency)
	Return a rate representing the given frequency. If the frequency is zero or too small, return min/max representable rate. More...
::ros::WallRate	cras::safeWallRate (double frequency)
	Return a rate representing the given frequency. If the frequency is zero or too small, return min/max representable rate. More...
