Struct LruModelCache 

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

LRU (Least Recently Used) cache for model elements

Thread-safe cache with automatic eviction of least recently used items.

Implementations

impl<T> LruModelCache<T>

where T: Clone,

pub fn new(capacity: usize) -> Self

Create a new LRU cache with specified capacity

Arguments

• capacity - Maximum number of items to cache

Example

use oxirs_samm::cache::LruModelCache;
use oxirs_samm::metamodel::Aspect;

let cache: LruModelCache<Aspect> = LruModelCache::new(50);
assert_eq!(cache.capacity(), 50);

pub fn get(&self, key: &str) -> Option<Arc<T>>

Get an item from the cache

Updates access statistics and LRU ordering.

pub fn put(&mut self, key: String, value: Arc<T>)

Put an item into the cache

If the cache is at capacity, evicts the least recently used item.

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

Check if the cache contains a key

pub fn remove(&mut self, key: &str) -> Option<Arc<T>>

Remove an item from the cache

pub fn clear(&mut self)

Clear all items from the cache

pub fn len(&self) -> usize

Get the number of items in the cache

pub fn is_empty(&self) -> bool

Check if the cache is empty

pub fn capacity(&self) -> usize

Get the cache capacity

pub fn resize(&mut self, new_capacity: usize)

Resize the cache capacity

If the new capacity is smaller than current size, evicts LRU items.

pub fn hit_rate(&self) -> f64

Get cache hit rate (0.0 to 1.0)

pub fn hits(&self) -> usize

Get total number of cache hits

pub fn misses(&self) -> usize

Get total number of cache misses

pub fn reset_statistics(&mut self)

Reset cache statistics

pub fn keys(&self) -> Vec<String>

Get all keys in the cache (in LRU order)

pub fn statistics(&self) -> CacheStatistics

Get cache statistics

Trait Implementations

impl<T> Clone for LruModelCache<T>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.
