Struct Store 

pub struct Store { /* private fields */ }

The content-addressed store rooted at $VANTA_HOME.

Implementations

impl Store

pub fn open(home: impl AsRef<Path>) -> VtaResult<Store>

Open (creating the directory skeleton if needed) a store at home.

pub fn store_dir(&self) -> PathBuf

pub fn downloads_dir(&self) -> PathBuf

pub fn envs_dir(&self) -> PathBuf

pub fn entry_path(&self, key: &StoreKey) -> PathBuf

The directory a store key occupies.

pub fn has(&self, key: &StoreKey) -> bool

Whether the store already contains an entry for key.

pub fn new_staging(&self) -> VtaResult<PathBuf>

Create a fresh, unique staging directory under the store. The installer unpacks into it, then calls Store::publish_tree.

pub fn publish_tree(&self, staged: &Path) -> VtaResult<StoreKey>

Publish a staged tree into the store, content-addressed and atomically. If an identical entry already exists, the staged copy is discarded (dedup) and the existing key returned.

pub fn verify_entry(&self, key: &StoreKey) -> VtaResult<bool>

Re-hash an entry and confirm it still matches its key (integrity check).

pub fn cache_put_blob(&self, bytes: &[u8]) -> VtaResult<String>

Store a downloaded blob in the content-addressed download cache, returning its blake3-<hex> cache key. Idempotent.

pub fn cache_get_path(&self, cache_key: &str) -> Option<PathBuf>

The path of a cached blob, if present.

pub fn gc(&self, roots: &HashSet<StoreKey>) -> VtaResult<usize>

Garbage-collect: remove every store entry not reachable from roots, plus stale staging dirs. Returns the number of entries removed.
