kafka consumer get current position

[Sunnycheey]

Hi, I create TopicPartition vector v1 and assign it to a kafka consumer. Currently, I want use position function to retrieve current offset of the KafkaConsumer. Can I call position directly on v1, or need I get assignment v2 of the KafkaConsumer first and then call postition on v2 since position call will change the input TopicPartition vector.
