Struct DeliveredId 

pub struct DeliveredId {
    pub boot: u64,
    pub id: u64,
}

The server’s id for a delivered message, with the boot it was drawn in.

id is the number the publisher’s PublishAck carried and the console’s tap id names; it is drawn from a counter that restarts on every boot, so boot (the server incarnation’s start, in wall-clock milliseconds since the epoch) says which run of the server the number belongs to. A reply that names a request does so by both, and a tap pairs it only within its own boot.

Fields

boot: u64

The server incarnation’s start, in wall-clock milliseconds since the epoch.

id: u64

The server’s message id within that boot.

Implementations

impl DeliveredId

pub fn reply_parent(self) -> MessageId

The causal parent a reply to this message names: <boot>:<id>, both in decimal. It is the tap id’s number with the boot in place of the device (Hermes 7 Oct 08:12), so a tap pairs a reply only within its own boot.

pub fn from_parent(parent: &MessageId) -> Option<Self>

The message a reply’s parent names, when the parent is exactly the form DeliveredId::reply_parent writes; any other form names none. Reads without allocating, because a tap reads it once per reply.
