Module cache 

Caching layer for node execution results

This module provides a flexible caching system for storing and retrieving node execution results to avoid redundant computations.

Features

• Node Result Caching: Store results keyed by node ID and input hash
• Cache Invalidation: LRU, FIFO, and manual invalidation strategies
• TTL Support: Automatic expiration of cached entries
• Memory Limits: Configurable memory bounds with automatic eviction

Example

use rust_logic_graph::cache::{CacheManager, CacheConfig, EvictionPolicy};
use std::time::Duration;

let config = CacheConfig {
    max_entries: 1000,
    max_memory_bytes: 100 * 1024 * 1024, // 100MB
    default_ttl: Some(Duration::from_secs(300)),
    eviction_policy: EvictionPolicy::LRU,
    enable_background_cleanup: true,
};

let cache = CacheManager::new(config).await?;

// Cache is automatically integrated with the executor
