Struct Publication 

pub struct Publication {
    pub id: String,
    pub topic: String,
    pub delivered: usize,
}

A published message, as the publisher hears about it.

Fields

id: String

Id of the first row written. A message with several subscribers has several rows and several ids; this is the one to quote in a log line.

topic: String

delivered: usize

How many subscribers it was queued for. Zero is not an error — the message is still recorded — but it is almost always a typo in a topic name, so a publisher that cares should look at it.
