Expand description
Per-instance counters: hits, misses, evictions, admissions, and shard-contention events.
Wraps the base BlockCache and adds atomic counters around get /
put. Use this when you want a single-instance summary; for system-
wide histograms reach for subms-hdr-histogram.
All counters are AtomicU64 so the cache is Send + Sync and can
be wrapped in Arc for multi-threaded summary reads even when the
cache itself is single-writer.
