Struct LruCacheConfig

pub struct LruCacheConfig { /* private fields */ }

Configuration for an LRU (Least Recently Used) cache.

LRU evicts the least recently accessed items when the cache reaches capacity.

Examples

use cache_rs::config::lru::LruCacheConfig;
use core::num::NonZeroUsize;

// Create a config with capacity of 100 items
let config = LruCacheConfig::new(NonZeroUsize::new(100).unwrap());

assert_eq!(config.capacity(), NonZeroUsize::new(100).unwrap());
