Struct FileCheckpointStorage 

pub struct FileCheckpointStorage { /* private fields */ }

File-system backed checkpoint storage.

Persists each Checkpoint to its own file under a root directory using the Pure-Rust oxicode binary codec (no C FFI, no external services). This is a real, durable CheckpointStorage implementation suitable for local fault-tolerant recovery.

Implementations

impl FileCheckpointStorage

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

Create a new file-backed checkpoint store rooted at root.

The directory (and any missing parents) is created if it does not exist.
