Enum SeriesState 

pub enum SeriesState {
    Live,
    Quiet,
    Evicted,
    OriginDown,
    Retired,
}

Why a series is, or is not, current (RFC 13 §3 — “a series that stopped is not a series that went quiet”).

Variants

Live

Fed, and nothing has said it stopped. For telemetry, which declares no period, this is all an observer can say — last_seen_unix_s carries the fact.

Quiet

A state subject silent past its declared ttl_s. Judged only where the registry declares the period; never for telemetry (O4).

Evicted

The observer chose to forget the key at its own bound (O6); the labels are kept so the disappearance is named.

OriginDown

The producer’s alive token went away (RFC 04 §5) after this series was fed.

Retired

The producer retired the key with a tombstone (RFC 04 §1.2) — its own statement, which outranks every inference above.
