Struct LruCacheMetrics

pub struct LruCacheMetrics {
    pub core: CoreCacheMetrics,
}

LRU-specific metrics (extends CoreCacheMetrics)

This struct contains metrics specific to the LRU (Least Recently Used) cache algorithm. Currently, LRU uses only the core metrics, but this structure allows for future LRU-specific metrics to be added.

Fields

core: CoreCacheMetrics

Core metrics common to all cache algorithms

Implementations

impl LruCacheMetrics

pub fn new(max_cache_size_bytes: u64) -> Self

Creates a new LruCacheMetrics instance with the specified maximum cache size

Arguments

• max_cache_size_bytes - The maximum allowed cache size in bytes

pub fn to_btreemap(&self) -> BTreeMap<String, f64>

Converts LRU metrics to a BTreeMap for reporting

This method returns all metrics relevant to the LRU cache algorithm. Currently, this includes only core metrics, but LRU-specific metrics could be added here in the future.

Uses BTreeMap to ensure consistent, deterministic ordering of metrics.

Returns

A BTreeMap containing all LRU cache metrics as key-value pairs

Trait Implementations

impl CacheMetrics for LruCacheMetrics

fn metrics(&self) -> BTreeMap<String, f64>

Returns all LRU cache metrics as key-value pairs in deterministic order

Returns

A BTreeMap containing all metrics tracked by this LRU cache instance

fn algorithm_name(&self) -> &'static str

Returns the algorithm name for this cache implementation

Returns

“LRU” - identifying this as a Least Recently Used cache

impl Clone for LruCacheMetrics

fn clone(&self) -> LruCacheMetrics

Returns a duplicate of the value.
