Struct cached::stores::UnboundCache

pub struct UnboundCache<K, V> { /* fields omitted */ }

Default unbounded cache

This cache has no size limit or eviction policy.

Note: This cache is in-memory only

Methods

impl<K: Hash + Eq, V> UnboundCache<K, V>

pub fn new() -> UnboundCache<K, V>

Creates an empty UnboundCache

pub fn with_capacity(size: usize) -> UnboundCache<K, V>

Creates an empty UnboundCache with a given pre-allocated capacity

Trait Implementations

impl<K: Hash + Eq, V> Cached<K, V> for UnboundCache<K, V>

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

Attempt to retrieve a cached value

fn cache_set(&mut self, key: K, val: V)

Insert a key, value pair

fn cache_remove(&mut self, k: &K) -> Option<V>

fn cache_size(&self) -> usize

Return the current cache size (number of elements)

fn cache_hits(&self) -> Option<u32>

Return the number of times a cached value was successfully retrieved

fn cache_misses(&self) -> Option<u32>

Return the number of times a cached value was unable to be retrieved

fn cache_capacity(&self) -> Option<usize>

Return the cache capacity

fn cache_lifespan(&self) -> Option<u64>

Return the lifespan of cached values (time to eviction)
