Implementations

impl RecoveryManager

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

Create a new recovery manager with the given configuration

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

Recover records from WAL

This method:

1. Reads all records from all WAL segments
2. Tracks transaction boundaries
3. Only returns records from committed transactions
4. For records outside transactions, returns them directly

Returns a vector of recovered records in order

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

Recover records with transaction markers included

Unlike recover(), this method returns all records including BEGIN_TX and COMMIT_TX markers for committed transactions. This is useful for replaying the exact WAL state.

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

Get statistics about the WAL
