Type	Name
void	check_and_handle_scan_complete (const std::vector< uint8_t > & packet, double packet_seconds, const uint32_t phase) Checks if the current packet completes the ongoing scan. TODO: this has been moved from velodyne_hw_interface.cpp and is a temporary solution until the Velodyne decoder uses the same structure as Hesai/Robosense.
