Cache Backend Implementations

This module contains all cache backend implementations for the multi-tier cache system.

Available Backends

In-Memory (L1 Tier)

• Moka - High-performance concurrent cache with automatic eviction (default L1)
• DashMap - Simple concurrent HashMap-based cache
• QuickCache - Lightweight, optimized for maximum performance (feature: backend-quickcache)

Distributed (L2 Tier)

• Redis - Industry-standard distributed cache with persistence (default L2)
• Memcached - Lightweight distributed cache (feature: backend-memcached)

On-Disk (L3/L4 Tier)

• RocksDB - Embedded persistent key-value store (coming soon)

Usage

use multi_tier_cache::backends::{MokaCache, RedisCache};

// Explicit backend selection
let moka = MokaCache::new().await?;
let redis = RedisCache::new().await?;

// Or use type aliases for backward compatibility
use multi_tier_cache::backends::{L1Cache, L2Cache};
let l1 = L1Cache::new().await?;  // MokaCache
let l2 = L2Cache::new().await?;  // RedisCache

Re-exports
