Struct WorkerCache 

pub struct WorkerCache<K, V>
where
    K: Hash + Eq + Clone,
{ /* private fields */ }

A simple per-worker cache to avoid repeated allocations.

Each worker maintains its own cache, eliminating contention.

Implementations

impl<K, V> WorkerCache<K, V>

where K: Hash + Eq + Clone,

pub fn new(max_entries: usize) -> Self

Create a new cache with max entries.

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

Get a value from the cache.

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

Get a mutable value from the cache.

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

Insert a value into the cache.

If at capacity, evicts a random entry.

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

Remove a value from the cache.

pub fn contains(&self, key: &K) -> bool

Check if key exists.

pub fn clear(&mut self)

Clear the cache.

pub fn len(&self) -> usize

Get cache size.

pub fn is_empty(&self) -> bool

Check if empty.

pub fn hits(&self) -> u64

Get hit count.

pub fn misses(&self) -> u64

Get miss count.

pub fn hit_ratio(&self) -> f64

Get hit ratio.
