sig_cache

Content-addressed caching for deterministic backtesting in sigc.

Overview

sig_cache provides a high-performance caching layer that ensures reproducible backtest results:

• Content-addressed storage - Uses Blake3 hashing for cache keys
• Deterministic outputs - Same inputs always produce same outputs
• Persistent storage - Uses sled for fast embedded database
• Zero-copy serialization - Uses rkyv for efficient serialization

Usage

use sig_cache::Cache;

let cache = Cache::new("~/.sigc/cache")?;

// Cache compiled plans
let key = cache.hash(&input);
if let Some(cached) = cache.get(&key)? {
    return Ok(cached);
}

let result = expensive_computation()?;
cache.put(&key, &result)?;
