Struct InMemoryNonceStore 

pub struct InMemoryNonceStore { /* private fields */ }

In-memory nonce store. One mutex; the working set is bounded by the clock-skew window — a 5-minute skew at 10k req/s caps at ~3M entries, which is fine. Production multi-replica deployments swap in Redis.

Implementations

impl InMemoryNonceStore

pub fn new() -> Self

Trait Implementations

impl Clone for InMemoryNonceStore

fn clone(&self) -> InMemoryNonceStore

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for InMemoryNonceStore

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

Formats the value using the given formatter.

impl Default for InMemoryNonceStore

fn default() -> InMemoryNonceStore

Returns the “default value” for a type.

impl NonceStore for InMemoryNonceStore

fn record_if_unseen<'life0, 'life1, 'async_trait>( &'life0 self, nonce: &'life1 str, expires_at: DateTime<Utc>, ) -> Pin<Box<dyn Future<Output = Result<bool, CoolError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Attempt to register nonce as seen. Returns Ok(true) if it is the first time we see it (caller may proceed); Ok(false) if it was already recorded (caller should reject). Implementations must drop entries past expires_at to keep the working set bounded.
