Expand description

Writer for disk cache of a hybrid cache to support more flexible write APIs.

Implementations§

source §

impl<K, V, S> HybridCacheStorageWriter<K, V, S>
where K: StorageKey, V: StorageValue, S: HashBuilder + Debug,

source

pub fn pick(&mut self) -> bool

Check if the entry can be admitted by the admission picker of the disk cache.

pick is idempotent (unless force is called). Which means the disk cache only check its admission at most once.

source

pub fn force(self) -> Self

Force the disk cache to admit the writer.

source

pub fn insert(self, value: V) -> Option<HybridCacheEntry<K, V, S>>

Insert the entry to the disk cache only.

source

pub fn insert_with_context( self, value: V, context: CacheContext, ) -> Option<HybridCacheEntry<K, V, S>>

Insert the entry with context to the disk cache only.
