pub struct IdempotencyStore { /* private fields */ }

A deduplication store that tracks recently processed idempotency keys. Stored in ClusterState and replicated via Raft.

Implementations

impl IdempotencyStore

pub fn new() -> Self

pub fn check(&self, key: &str) -> Option<&str>

Check if an idempotency key has already been processed. Returns the cached response if it has, None if it hasn’t.

pub fn record(&mut self, key: String, response: String)

Record that an idempotency key has been processed with the given response.

pub fn record_with_ttl(&mut self, key: String, response: String, ttl_secs: i64)

Record with a custom TTL.

pub fn gc(&mut self)

Garbage collect expired entries. Call periodically.

pub fn len(&self) -> usize

Number of active (non-expired) entries.

pub fn is_empty(&self) -> bool
