Struct FixedDiscoveryValidationCache 

pub struct FixedDiscoveryValidationCache<const VALID: usize, const INSUFFICIENT: usize, const MAX_PACKED_BYTES: usize, const VALID_BUCKETS: usize, const INSUFFICIENT_BUCKETS: usize> { /* private fields */ }

Inline, allocation-free discovery validation caches for embedded and custom storage profiles.

Each cache is independently FIFO-bounded and uses stable ring slots plus a Lemire side index. A valid advertisement larger than MAX_PACKED_BYTES is simply not memoized; it still passes through normal validation. The bucket counts must provide the headroom returned by discovery_validation_index_buckets. FixedDiscoveryValidationCache<0, 0, 0, 1, 1> disables memoization without disabling discovery.
