Struct SnapshotStore 

pub struct SnapshotStore { /* private fields */ }

Content-addressed snapshot store

Implementations

impl SnapshotStore

pub fn new(root: impl Into<PathBuf>) -> Result<Self>

pub fn put_blob(&self, data: &[u8]) -> Result<HashDigest>

pub fn get_blob(&self, hash: &HashDigest) -> Result<Vec<u8>>

pub fn put_struct<T: Serialize>(&self, value: &T) -> Result<HashDigest>

pub fn get_struct<T: for<'de> Deserialize<'de>>( &self, hash: &HashDigest, ) -> Result<T>

pub fn put_snapshot(&self, snapshot: &ExecutionSnapshot) -> Result<HashDigest>

pub fn get_snapshot(&self, hash: &HashDigest) -> Result<ExecutionSnapshot>

pub fn list_snapshots(&self) -> Result<Vec<(HashDigest, ExecutionSnapshot)>>

List all snapshots in the store, returning (hash, snapshot) pairs.

Note: This method eagerly loads and deserializes every snapshot in the store directory into memory. For stores with many snapshots this may become a bottleneck. A future improvement could return a lazy iterator that streams snapshot metadata (hash + created_at_ms) without deserializing full payloads until requested — e.g. via a SnapshotEntry { hash, created_at_ms } header read, deferring full ExecutionSnapshot deserialization to an explicit .load() call.

pub fn delete_snapshot(&self, hash: &HashDigest) -> Result<()>

Delete a snapshot file by hash.

Trait Implementations

impl Clone for SnapshotStore

fn clone(&self) -> SnapshotStore

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
