graphyn-store

Persistence and hot-cache crate for Graphyn.

graphyn-store persists graph snapshots into RocksDB and provides an in-memory hot query cache for fast repeated lookups.

Responsibilities

• Save/load GraphynGraph snapshots (RocksGraphStore)
• Snapshot conversion (GraphSnapshot)
• In-memory cache for query results (HotQueryCache)

Main APIs

• RocksGraphStore::open(path)
• RocksGraphStore::save_graph(&graph)
• RocksGraphStore::load_graph()
• HotQueryCache::{new, put, get, invalidate, clear, stats}

Minimal usage

use std::path::Path;
use graphyn_store::RocksGraphStore;

let store = RocksGraphStore::open(Path::new(".graphyn/db"))?;
let _graph = store.load_graph()?;
# Ok::<(), Box<dyn std::error::Error>>(())

Notes

• Snapshot encoding is binary and round-trip safe for literal backslash sequences.
• Storage concerns are isolated here; graph/query logic stays in graphyn-core.
