Thread-safe bounded LRU response cache.

Implementations

impl ResponseCache

pub fn new(capacity: usize, ttl: Duration) -> Self

Creates a cache with the requested capacity and defaulting zero TTLs.

Capacity is clamped to the inclusive range 1..=512.

pub fn with_ttl(ttl: Duration) -> Self

Creates a cache with the requested TTL and the maximum capacity.

pub fn set_policy(&mut self, policy: CachePolicy)

Replaces the cache expiry policy for existing and future entries.

pub fn get(&self, key: &ResponseCacheKey) -> Option<CachedResponse>

Looks up a response, refreshing its LRU position on a live hit.

pub fn put(&self, key: ResponseCacheKey, response: CachedResponse)

Inserts or replaces a response, evicting the least recently used entry when the bounded capacity is reached.

pub fn stats(&self) -> CacheStats

Returns cumulative hit, miss, and eviction counters.
