[rabbitmq-discuss] extremely long and weird delivery tag in amqp.js consumer

[Jianhui Zhang]

Hi,

We are using amqp.js library to consume messages from rabbitmq. But when we
log the delivery tag, we found them extremely long and weird (aren't they
supposed to be a long int?). For example:

"deliveryTag":{"0":0,"1":0,"2":0,"3":0,"4":0,"5":0,"6":0,"7":1,"length":8,"parent":{"0":60,"1":33,"2":68,"3":79,"4":67,"5":84,"6":89,"7":80,"8":69,"9":
