我想在rabbitmq中传输文件，发现rabbit_framing.hrl文件中的消息记录如下。但是这些消息没有解释指南。使用这些消息效率低还是我没有找到相关信息？
你能给我一些使用这些消息的示例代码吗？
-record('file.qos', {prefetch_size = 0, prefetch_count = 0, global = false}).
-record('file.qos_ok', {}).
-record('file.consume', {ticket = 1, queue = <<"">>, consumer_tag = <<"">>, no_local = false, no_ack = false, exclusive = false, nowait = false}).
-record('file.consume_ok', {consumer_tag}).
-record('file.cancel', {consumer_tag, nowait = false}).
-record('file.cancel_ok', {consumer_tag}).
-record('file.open', {identifier, content_size}).
-record('file.open_ok', {staged_size}).
-record('file.stage', {}).
-record('file.publish', {ticket = 1, exchange = <<"">>, routing_key = <<"">>, mandatory = false, immediate = false, identifier}).
-record('file.return', {reply_code = 200, reply_text = <<"">>, exchange, routing_key}).
-record('file.deliver', {consumer_tag, delivery_tag, redelivered = false, exchange, routing_key, identifier}).
-record('file.ack', {delivery_tag = 0, multiple = false}).
-record('file.reject', {delivery_tag, requeue = true}).
