pub struct Cache<T: 'static> { /* private fields */ }

Cache for each Writium Api. Any Writium Api can be composited with this struct for cache.

Implementations

impl<T: 'static> Cache<T>

pub fn new<Src>(capacity: usize, src: Src) -> Cache<T>

where Src: 'static + CacheSource<Value = T>,

pub fn create(&self, id: &str) -> Result<Arc<CacheItem<T>>>

Get the object identified by given ID. If the object is not cached, try recovering its cache from provided source. If there is no space for another object, the last recently accessed cache will be disposed.

pub fn get(&self, id: &str) -> Result<Arc<CacheItem<T>>>

Get the object identified by given ID. If the object is not cached, error will be returned. If there is no space for another object, the last recently accessed cache will be disposed.

pub fn remove(&self, id: &str) -> Result<()>

Remove the object identified by given ID.

Trait Implementations

impl<T: 'static> Drop for Cache<T>
