Struct RotationLog 

pub struct RotationLog { /* private fields */ }

The append-only rotation log in a manifest store.

Implementations

impl RotationLog

pub fn new(dir: &Path) -> Self

The log for the manifest store dir.

pub fn path(&self) -> &Path

File path.

pub fn read(&self) -> Result<Vec<RotationRecord>, RotationError>

Every record. A missing file is an empty log; an unreadable or unparseable one is an error (fail closed).

pub fn history( &self, current: &[u8; 32], ) -> Result<UserKeyHistory, RotationError>

The history for current: single when the log is empty.

pub fn replace(&self, records: &[RotationRecord]) -> Result<(), RotationError>

Replace the whole log with records (the chain’s copy, for rebuilding a deleted or truncated file). The records must form one history.

pub fn append(&self, record: &RotationRecord) -> Result<(), RotationError>

Append record (the whole file is rewritten atomically, 0600). The record must extend the existing log.
