Struct CommittedTxReader 

pub struct CommittedTxReader { /* private fields */ }

Lazily yields committed transactions whose TxBegin LSN is above after and whose commit LSN is at or below upto.

Records past upto are never decoded, so the reader is safe to use while a writer keeps appending to the active segment: everything at or below upto was written to the OS before upto was observed.

Implementations

impl CommittedTxReader

pub fn open(dir: &Path, after: Lsn, upto: Lsn) -> Result<Self, WalError>

pub fn next_tx(&mut self) -> Result<Option<CommittedTx>, WalError>

Next committed transaction, or None once upto is reached or the log ends.
