Trait Implementations

impl Clone for MemoryCacheLifecycle

fn clone(&self) -> MemoryCacheLifecycle

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Lifecycle<CacheKey, Arc<RwLock<Vec<CachedResource>>>> for MemoryCacheLifecycle

type RequestState = ()

fn begin_request(&self) -> Self::RequestState

Called before the insert request starts, e.g.: insert, replace.

fn on_evict( &self, _state: &mut Self::RequestState, key: CacheKey, value: Arc<RwLock<Vec<CachedResource>>>, )

Called when an item is evicted.

fn is_pinned(&self, key: &Key, val: &Val) -> bool

Returns whether the item is pinned. Items that are pinned can’t be evicted. Note that a pinned item can still be replaced with get_mut, insert, replace and similar APIs.

fn before_evict(&self, state: &mut Self::RequestState, key: &Key, val: &mut Val)

Called when a cache item is about to be evicted. Note that value replacement (e.g. insertions for the same key) won’t call this method.

fn on_evict_cold(&self, state: &mut Self::RequestState, key: Key, val: Val)

Called when an item is evicted from the cold queue.

fn on_evict_hot(&self, state: &mut Self::RequestState, key: Key, val: Val)

Called when an item is evicted from the hot queue.

fn end_request(&self, state: Self::RequestState)

Called after a request finishes, e.g.: insert, replace.
