Struct PreparedTxnEntry 

pub struct PreparedTxnEntry { /* private fields */ }

A validated, _seq-assigned, serialized log line produced by Table::prepare_txn_ops — nothing on disk yet, but everything needed to journal it and, later, to append it.

Implementations

impl PreparedTxnEntry

pub fn seq(&self) -> u64

pub fn line(&self) -> &str

pub fn old(&self) -> Option<&HaysonRecord>

pub fn record(&self) -> Option<&HaysonRecord>

pub fn upsert_event(&self) -> TriggerEvent

Insert when no old record existed, Update otherwise — a Delete is never produced here, since a caller telling insert/update apart from delete already knows which TxnOp it staged; use it against TxnOp::Put/TxnOp::Patch results only.
