Struct LruCacheStore 

pub struct LruCacheStore { /* private fields */ }

Bounded in-process cache store using least-recently-used eviction.

Implementations

impl LruCacheStore

pub fn new(capacity: usize) -> CacheResult<Self>

Creates a bounded LRU store.

pub fn capacity(&self) -> usize

Returns the configured capacity.

pub fn with_metrics(self, metrics: MetricsRegistry) -> Self

Attaches a metrics registry to this L1 cache store.

pub async fn snapshot(&self) -> LruCacheSnapshot

Removes expired entries and returns the current snapshot.
