Struct LfuCacheConfig

pub struct LfuCacheConfig { /* private fields */ }

Configuration for an LFU (Least Frequently Used) cache.

LFU tracks the frequency of access for each item and evicts the least frequently used items when the cache reaches capacity.

Examples

use cache_rs::config::lfu::LfuCacheConfig;
use core::num::NonZeroUsize;

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

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