Implementations

impl WriteAheadLog

pub fn open(path: &Path) -> Result<Self>

pub fn append(&mut self, entry: &WalEntry) -> Result<()>

pub fn append_batch(&mut self, entries: &[WalEntry]) -> Result<()>

Append many entries with a single sync_all at the end. Used by bulk load, where per-entry fsync would dominate (one fsync per vector). The batch is still crash-consistent: on a crash mid-batch, replay stops at the last fully-written entry (length/checksum framing), and any partial tail is ignored.

pub fn replay(&mut self) -> Result<Vec<WalEntry>>

pub fn checkpoint(&mut self) -> Result<()>

pub fn truncate_after_checkpoint(&mut self) -> Result<()>

pub fn entry_count(&self) -> usize
