what is exactly Publisher confirms in Rabbitmq?

I read the official document of Rabbitmq, it is not really clear for me what was that? its something like Consumer Ack but with a difference that the Publisher Confirm is send by rabbitmq server to Publisher client when the server get the message from publisher client?

Can someone explain more about it?

thanks in advance.

Yes. When you enable publisher confirms, and your publisher receives acknowledgement that the message is published, you can be certain of it.

Without publisher confirms, you can lose messages in several cases. One example: your application could publish the data to the TCP buffer, but then crash, or the server itself could crash. Another example: a network device could fail mid-delivery. Another example: RabbitMQ itself could crash after receiving the TCP data containing your message.
