Struct BoundedReplayStore 

pub struct BoundedReplayStore { /* private fields */ }

Process-local TTL replay store with LRU ordering and fail-closed capacity.

Live entries are never evicted merely to make space because doing so would reopen their replay window. LRU ordering is used to remove expired entries deterministically; a full live set rejects new requests.

Implementations

impl BoundedReplayStore

pub fn new(config: ReplayStoreConfig) -> Self

Creates an empty bounded replay store.

Trait Implementations

impl Debug for BoundedReplayStore

fn fmt(&self, f: &mut Formatter<'_>) -> Result

impl PeerNonceStore for BoundedReplayStore

fn check_and_record( &self, nonce: &str, expires_at_ms: u64, now_ms: u64, ) -> Result<(), PeerRpcError>

Rejects a live duplicate or records the nonce until expires_at_ms.

impl ReplayStore for BoundedReplayStore

fn cleanup(&self, now_ms: u64) -> Result<usize, PeerRpcError>
