Struct MemoCache 

pub struct MemoCache<T> { /* private fields */ }

MemoCache is a struct that represents a cache with a set capacity. It uses an LRU (Least Recently Used) eviction policy.

Implementations

impl<T> MemoCache<T>

pub fn capacity(&self) -> usize

Capacity returns the capacity of the MemoCache.

pub fn size(&self) -> usize

Size returns the current size of the MemoCache. It is the number of items currently stored in the cache.

pub fn get<H: Hasher>(&mut self, h: &H) -> Option<&T>

Get returns the value associated with the given hashable item in the MemoCache. If there is no corresponding value, the method returns None.

pub fn set<H: Hasher>(&mut self, h: &H, value: T)

Set sets the value for the given hashable item in the MemoCache. If the cache is at capacity, it evicts the least recently used item before adding the new item.
