Struct MemoryCache 

pub struct MemoryCache { /* private fields */ }

In-memory cache implementation

Implementations

impl MemoryCache

pub fn new() -> Self

pub fn with_default_ttl(ttl: Duration) -> Self

pub async fn remember<T, F, Fut>( &self, key: &str, ttl: Duration, f: F, ) -> Result<T>

where T: Serialize + for<'de> Deserialize<'de> + Send + Sync, F: FnOnce() -> Fut + Send, Fut: Future<Output = Result<T>> + Send,

Remember a value, executing the closure if not cached

pub fn stats(&self) -> CacheStats

Snapshot in-memory cache operation counters.

pub fn reset_stats(&self)

Reset cache operation counters.
