Crate synaptic_sqlite 

SQLite integration for the Synaptic framework.

This crate provides:

• SqliteCache: A SQLite-backed implementation of the LlmCache trait for caching LLM responses with optional TTL expiration.
• SqliteCheckpointer: A SQLite-backed implementation of the Checkpointer trait for persisting graph state between executions.

Quick start

use synaptic_sqlite::{SqliteCache, SqliteCacheConfig};

// In-memory cache (great for testing)
let cache = SqliteCache::new(SqliteCacheConfig::in_memory())?;

// File-based cache with 1-hour TTL
let config = SqliteCacheConfig::new("/tmp/llm_cache.db").with_ttl(3600);
let cache = SqliteCache::new(config)?;
