Write-ahead log for crash recovery

Implementations§

Source§

impl WriteAheadLog

Source

pub fn open(dir: &Path) -> Result<Self, Error>

Open or create WAL

Source

pub fn write(&mut self, block: &Block) -> Result<(), Error>

Write entry to WAL (before main log)

Source

pub fn commit(&mut self, _sequence: u64) -> Result<(), Error>

Mark entry as committed (can be garbage collected)

Source

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

Recover uncommitted entries after crash (handles WAL corruption gracefully)

Source

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

Clear WAL after successful checkpoint
