Struct MemoryReplayStore 

pub struct MemoryReplayStore { /* private fields */ }

In-memory replay protection store for environments without Redis.

Tracks seen kx hashes for a configurable TTL and prunes expired entries on each check. Wrap in Arc (via MemoryReplayStore::new) and share across all Actix workers via Interceptor.

Implementations

impl MemoryReplayStore

pub fn new(ttl: Duration) -> Arc<Self>

Creates an Arc-wrapped store whose entries expire after ttl.

pub async fn is_new(&self, key: &str) -> bool

Returns true if key is new (not seen within ttl), inserting it. Returns false on replay. Prunes expired entries on every call.
