Struct LogicalWalSpool 

pub struct LogicalWalSpool { /* private fields */ }

Durable append-only logical WAL spool kept beside the main .rdb file.

This is not the storage-engine WAL; it is a structured replication/PITR log.

Implementations

impl LogicalWalSpool

pub fn path_for(data_path: &Path) -> PathBuf

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

pub fn append(&self, lsn: u64, data: &[u8]) -> Result<()>

pub fn append_with_timestamp( &self, lsn: u64, timestamp_ms: u64, data: &[u8], ) -> Result<()>

Append a record with an explicit framing timestamp. Used in tests to produce deterministic timestamps; production callers should use append.

pub fn read_since( &self, since_lsn: u64, max_count: usize, ) -> Result<Vec<(u64, Vec<u8>)>>

pub fn current_lsn(&self) -> u64

pub fn oldest_lsn(&self) -> Result<Option<u64>>

pub fn prune_through(&self, upto_lsn: u64) -> Result<()>
