Fields

producer: String

registry_version: String

class: String

path: String

type_name: String

open_ended: bool

Trailing {var...} family: the registry fixes the shape, not the members.

since: Option<String>

Registry version the subject first appeared in, when declared.

deprecated: bool

A retired subject (from the slice’s [[deprecated]] ledger, RFC 08 §6) — rendered only under topic list --deprecated.

deprecated_since: Option<String>

When it was retired, if the ledger says.

replaced_by: Option<String>

The declared replacement subject, if any.

cardinality: Option<i64>

The declared key-population bound (RFC 08 §2: mandatory on any {var} pattern; the budget review enforces). Additive (#221) — old consumers keep parsing.

budget: Option<BudgetCell>

Declared-vs-observed key population — present only under topic list --budget (#221).
