Struct RequestCache 

pub struct RequestCache<K, V>
where
    K: Hash + Eq + Clone + Send + Sync + 'static,
    V: Clone + Send + Sync + 'static,
{ /* private fields */ }

Thread-safe request cache with TTL and LRU eviction.

Implementations

impl<K, V> RequestCache<K, V>

where K: Hash + Eq + Clone + Send + Sync + 'static, V: Clone + Send + Sync + 'static,

pub fn new(max_size: usize, default_ttl: Duration) -> Self

Create a new request cache.

pub fn with_config(config: CacheConfig) -> Self

Create a new request cache with custom configuration.

pub async fn get(&self, key: &K) -> Option<V>

Get a value from the cache.

pub async fn insert(&self, key: K, value: V) -> Option<V>

Insert a value into the cache.

pub async fn insert_with_ttl( &self, key: K, value: V, ttl: Duration, ) -> Option<V>

Insert a value with custom TTL.

pub async fn remove(&self, key: &K) -> Option<V>

Remove a value from the cache.

pub async fn contains_key(&self, key: &K) -> bool

Check if the cache contains a key.

pub async fn len(&self) -> usize

Get the number of entries in the cache.

pub async fn is_empty(&self) -> bool

Check if the cache is empty.

pub async fn clear(&self)

Clear all entries from the cache.

pub fn statistics(&self) -> &CacheStatistics

Get cache statistics.

pub async fn cleanup_expired(&self) -> usize

Cleanup expired entries.

impl RequestCache<RequestCacheKey, Value>

pub fn new_api_cache() -> Self

Create a cache optimized for API requests.

pub async fn cache_response<I: Serialize, O: Serialize>( &self, endpoint: &str, method: &str, request_body: Option<&I>, headers: &HashMap<String, String>, response: &O, ) -> Result<()>

Cache an API response with separate request and response types.

Errors

Returns an error if cache key generation or value serialization fails.

pub async fn get_response<I: Serialize, O: for<'de> Deserialize<'de>>( &self, endpoint: &str, method: &str, request_body: Option<&I>, headers: &HashMap<String, String>, ) -> Result<Option<O>>

Get a cached API response with separate request and response types.

Errors

Returns an error if cache key generation or response deserialization fails.

impl<K, V> Debug for RequestCache<K, V>

where K: Hash + Eq + Clone + Send + Sync + 'static + Debug, V: Clone + Send + Sync + 'static + Debug,

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

Formats the value using the given formatter.
