def self.fetch(loader:, store:)
  # ADR-54 WD4 — the descriptor is identical for every producer consulting the same loader (same sig
  # files, same libraries), so the loader memoises one build per process instead of re-digesting every
  # .rbs file once per producer.
  descriptor = loader.rbs_cache_descriptor
  store.fetch_or_compute(producer_id: self::PRODUCER_ID, params: {}, descriptor: descriptor,
                         generation_cap: generation_cap) do
    compute(loader)
  end
end

.generation_cap ⇒ Integer

The generation cap this producer declares to Cache::Store#evict! (issue #151). rigor sig-gen infers the literal 2 from the base body; the contract is the wider Integer, since a subclass may override it.

Returns:

  • (Integer)
