Module drv_cache 

Content-addressed derivation path cache (redb-backed). Content-addressed derivation path cache.

Maps (lock_hash, source_hash, attr_path) → (drvPath, outPath) using redb. Survives process restarts. Designed to avoid full nixpkgs evaluation when the result is already known for a given flake.lock + flake.nix + attribute.

The cache file lives at ~/.cache/sui/drv-cache.redb by default.
