Struct AsyncLruCacheEntry

Source 
pub(crate) struct AsyncLruCacheEntry<V> {
    value: Option<Arc<V>>,
    last_used: AtomicUsize,
}
Expand description

Cache entry structure, wrapping the cached object.

Fields§

§value: Option<Arc<V>>

Cached object.

Always set during operation, only cleared when trying to unwrap the Arc on eviction.

§last_used: AtomicUsize

When this entry was last accessed.
