Module cache 

Advanced caching utilities with TTL and memory management.

This module provides caching structures with time-to-live (TTL) support, automatic eviction, and memory management for efficient data caching.

Examples

use chie_core::cache::TtlCache;
use std::time::Duration;

let mut cache = TtlCache::new(100, Duration::from_secs(60));

// Insert with TTL
cache.insert("key1".to_string(), "value1".to_string());

// Retrieve (returns cloned value)
assert_eq!(cache.get(&"key1".to_string()), Some("value1".to_string()));

// Entry expires after TTL
std::thread::sleep(Duration::from_millis(100));
// Still valid within TTL
assert!(cache.get(&"key1".to_string()).is_some());
