Source

pub fn sync_reclaim(&self)

Synchronous inline reclamation for Lock-based caches (e.g., StaticDualCache) that do not have a background daemon thread. MUST ONLY be called when protected by a Mutex to avoid data races on the single-consumer QSBR garbage queues.

Source

pub fn record_remote_hit(&self, hash: usize, _weight: u8)

Record a remote hit for an item based on its hash. Used by the Daemon to propagate TLS hits into the global T2 cache.
