pub const GCRA_STORE_SHARDS: usize = 16;Expand description
Number of independent shard locks in a GcraShardStore. Fixed (not
CPU-count-derived) so the worst-case key bound per window
(GCRA_STORE_SHARDS * MAX_RATE_LIMITER_KEYS_PER_SHARD) is the same
number on every machine. Public for the eviction tests’ bound
assertions.
