Struct crude_cache::CrudeCache

pub struct CrudeCache { /* private fields */ }

Implementations

impl CrudeCache

pub fn new(num_shards: usize) -> Self

• num_shards - Determines how many internal Shards (HashMaps) cache has. default() uses 64.

pub async fn force_insert<V>( &self, k: impl Into<String>, v: V, duration: Duration )where V: 'static + Sync + Send + Clone,

Inserts new value regardless of existing items expiration. Causes writelock for the shard

pub async fn get<V: 'static + Clone>(&self, key: &str) -> Option<V>

Gets the item by its key. If the value does not exist or it has expired, returns None.

Panics

Panics if value of the cached type is not V.

pub async fn get_or_else_update<V, F, Fut>( &self, key: &str, expiration: Duration, get: F ) -> Vwhere V: 'static + Clone + Sync + Send, F: Fn() -> Fut, Fut: Future<Output = V>,

Gets the item by its key. If the value does not exist or it has expired, new value by calling the provided get Fn.

Panics

Causes panic if value of the cached type is not V.
