Implementations

impl WalManager

pub fn new(config: WalConfig) -> Result<WalManager, Error>

pub fn open(&mut self) -> Result<(), Error>

Open the WAL for writing

This creates or opens the current WAL segment for appending records.

pub fn append(&mut self, record: WalRecord) -> Result<u64, Error>

Append a record to the WAL

pub fn sync(&mut self) -> Result<(), Error>

Sync the WAL to disk

pub fn close(&mut self) -> Result<(), Error>

Close the WAL

pub fn recover(&self) -> Result<Vec<WalRecord>, Error>

Recover records from the WAL

This reads all segments and returns committed records for replay. Incomplete transactions are rolled back (not included).

pub fn recover_with_markers(&self) -> Result<Vec<WalRecord>, Error>

Recover records with transaction markers included

Unlike recover(), this includes BEGIN_TX and COMMIT_TX markers.

pub fn stats(&self) -> Result<RecoveryStats, Error>

Get statistics about the WAL

pub fn reader(&self) -> Result<WalReader, Error>

Create a reader for the WAL

pub fn segment_manager(&self) -> SegmentManager

Get a segment manager for the WAL

pub fn config(&self) -> &WalConfig

Get the current configuration

pub fn is_open(&self) -> bool
