Trait Implementations

impl<S: Snapshot> Scanner for Scanner<S>[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.
