Struct AnalysisLruCache 

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

Generic thread-safe LRU cache with eviction tracking and poison recovery.

Wraps an LruCache in Arc<Mutex<...>> with an atomic eviction counter. Recovers gracefully from mutex poisoning by clearing the cache.

Implementations

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

pub fn new(capacity: usize) -> Self

Create a new AnalysisLruCache with the given capacity.

capacity is clamped to a minimum of 1 so a zero value does not panic.

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

Look up a cached result by key. Returns None on miss or mutex poison.

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

Store a key-value pair in the cache.

Uses LruCache::push to distinguish between insertions, updates of existing keys, and evictions of other entries. Eviction count only increments when a different key is evicted at capacity.

pub fn eviction_count(&self) -> u64

Returns the number of LRU evictions that have occurred in this cache.

Trait Implementations

impl<K: Hash + Eq + Clone, V: Clone> Clone for AnalysisLruCache<K, V>

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
