pub(crate) fn build_record(
instance: &WanInstance,
feed: &FleetFeed,
snapshot: &FleetSnapshot,
v: u32,
published_at_ms: u64,
) -> Option<InstallPresence>Expand description
The record for snapshot, as version v. An agent whose kind isn’t
known is left out: the record requires one, and the feed doesn’t guess.
An agent whose state isn’t known carries none, and one with no line no line.
