Struct DiskSnapshotStore 

pub struct DiskSnapshotStore { /* private fields */ }

Disk-backed snapshot store. Writes are atomic via the .tmp + rename dance in crate::atomic::write_atomic_bytes, with the parent directory fsynced on success.

Implementations

impl DiskSnapshotStore

pub fn new(path: PathBuf) -> Self

pub fn path(&self) -> &Path

Trait Implementations

impl SnapshotStore for DiskSnapshotStore

fn load(&self) -> Result<Option<Vec<u8>>>

Load the latest snapshot, if one exists. Returns Ok(None) when there is nothing on disk yet (first boot).

fn save(&self, bytes: &[u8]) -> Result<()>

Persist the given bytes as the new snapshot. Implementations must ensure the write is atomic (crash-safe) and durable.
