Forward(ForwardScanner<S, LatestKvPolicy>)Backward(BackwardKvScanner<S>)Trait Implementations
impl<S: Snapshot> Scanner for Scanner<S>[src]
fn next(&mut self) -> TxnResult<Option<(Key, Value)>>[src]
fn take_statistics(&mut self) -> Statistics[src]
Take out and reset the statistics collected so far.
fn met_newer_ts_data(&self) -> NewerTsCheckState[src]
Returns whether data with newer ts is found. The result is meaningful only when
check_has_newer_ts_data is set to true.
