Struct LockFreeCache 

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

Simple lock-free cache with fixed size

This cache uses atomic operations for thread-safe access without locks. It’s optimized for read-heavy workloads with occasional writes.

Implementations

impl<K: Eq + Hash + Clone, V: Clone> LockFreeCache<K, V>

pub fn new(capacity: usize) -> Self

Create a new lock-free cache with given capacity

pub fn capacity(&self) -> usize

Get the capacity

pub fn len(&self) -> usize

Get current size (approximate due to concurrency)

pub fn is_empty(&self) -> bool

Check if empty

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

Try to get a value from the cache

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

Check if a key exists in the cache
