Module range_cache 

Coordinates range-result cache loads and SST retirement. No I/O or decoding runs under the coordinator lock; loaders use the shared query runtime.

Structs

Entry 🔒

Flight 🔒

LoadGuard 🔒

Also unregisters a cancelled or panicking load. Generation matching keeps a stale task from unregistering a later retry of the same key.

RangeCacheDelivery 🔒

Keeps completed results charged while subscribers or replay streams own them. Cache entries retain only a weak reference: after the last reader leaves, the resident value is covered solely by the cache’s capacity accounting.

RangeCacheWorker 🔒

State 🔒

Enums

RangeCacheLookup 🔒

Constants

MAX_IN_FLIGHT_RANGES 🔒

Admission, not a queue: excess distinct misses keep using ordinary scans.
