Struct FileSyncCheckpointStore 

pub struct FileSyncCheckpointStore { /* private fields */ }

File-backed checkpoint store (line-based peer=sequence,hash).

Implementations

impl FileSyncCheckpointStore

pub fn new(file_path: impl Into<PathBuf>) -> SyncResult<Self>

Opens or creates an atomic line-based checkpoint file.

pub fn file_path(&self) -> &Path

Returns the durable checkpoint file path.
