Struct PublishFact 

pub struct PublishFact<'a> {
    pub subject: &'a str,
    pub payload: &'a [u8],
    pub outcome: TapOutcome,
    pub message_id: Option<u64>,
    pub source: TapSource,
    pub reply_to: Option<&'a str>,
    pub recorded: Option<Recorded<'a>>,
}

One publish as the hook hands it to the tap. Borrowed throughout: the tap copies only what an admitted message keeps.

Fields

subject: &'a str

The subject (channel name).

payload: &'a [u8]

The payload; its length is the message’s size, and it is copied only for a subscription holding a PayloadGrant.

outcome: TapOutcome

What became of it.

message_id: Option<u64>

The message id, when the publish was admitted and given one.

source: TapSource

Who published.

reply_to: Option<&'a str>

The id of the message it answers (the envelope’s causal parent).

recorded: Option<Recorded<'a>>

What the publish recorded; None when it recorded nothing: no tap was live when it began, or the tap could not lend it a record. The tap then first sees the message as it keeps it, and knows neither whom it reached nor when.
