Struct ShapingCache 

pub struct ShapingCache { /* private fields */ }

Cache for shaping results

Uses a two-level cache (L1 hot cache + L2 LRU cache) for optimal performance across different access patterns.

Implementations

impl ShapingCache

pub fn new() -> ShapingCache

Create a new shaping cache with default capacities

L1 (hot cache): 100 entries for frequently accessed results L2 (LRU cache): 500 entries for less frequent access

pub fn with_capacity(l1_size: usize, l2_size: usize) -> ShapingCache

Create a shaping cache with custom capacities

pub fn get(&self, key: &ShapingCacheKey) -> Option<ShapingResult>

Get a cached shaping result

Returns Some(result) if the key exists in either cache level, None if not found or if caching is globally disabled.

pub fn insert(&self, key: ShapingCacheKey, result: ShapingResult)

Insert a shaping result into the cache

The result is stored in both L1 and L2 caches for maximum availability. Does nothing if caching is globally disabled.

pub fn hit_rate(&self) -> f64

Get the current cache hit rate (0.0 to 1.0)

pub fn stats(&self) -> CacheStats

Get cache statistics
