Struct Cache

pub struct Cache<K, V, S, W: Weigher<K, V> = One, L: Lifecycle<K, V> = DefaultLifecycle> { /* private fields */ }

Implementations

impl<K, V, S, W, L> Cache<K, V, S, W, L>

where K: Eq + Hash + Clone, S: BuildHasher, W: Weigher<K, V>, L: Lifecycle<K, V> + Default,

pub fn new(hasher: S, max_weight: usize) -> Self

impl<K, V, S, W, L> Cache<K, V, S, W, L>

where K: Eq + Hash + Clone, S: BuildHasher, W: Weigher<K, V>, L: Lifecycle<K, V>,

pub fn new_with_lifecycle(hasher: S, max_weight: usize, lifecycle: L) -> Self

pub fn put(&mut self, key: K, value: V)

pub fn get<Q>(&self, key: &Q) -> Option<&V>

where K: Borrow<Q>, Q: Hash + Eq + ?Sized,

pub fn remove(&mut self, key: &K) -> Option<V>

pub fn evict_all(&mut self)

Clears the cache, via eviction.

If you want to handle the evicted entries, use the Lifecycle trait. The order of eviction is unspecified.

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
