Struct FileSnapshotStore 

pub struct FileSnapshotStore { /* private fields */ }

Filesystem-based SnapshotStore with atomic write semantics.

Snapshots are serialized as JSON files. Each write first goes to a .tmp file and is then atomically renamed to the final path, preventing partial snapshots from being visible to concurrent readers.

Implementations

impl FileSnapshotStore

pub fn new(base_dir: PathBuf) -> Self

Creates a new filesystem-backed snapshot store in the given directory.
