snapshot: Sfill_cache: boolomit_value: boolisolation_level: IsolationLevellower_bound: Option<Key>

lower_bound and upper_bound is used to create default_cursor. upper_bound is used in initial seek(or lower_bound in initial backward seek) as well. They will be consumed after default_cursor is being created.

Implementations

`impl<S: Snapshot> ScannerConfig<S>`[src]

`fn new(snapshot: S, ts: TimeStamp, desc: bool) -> Self`[src]

`fn scan_mode(&self) -> ScanMode`[src]

`fn create_cf_cursor(&mut self, cf: CfName) -> Result<Cursor<S::Iter>>`[src]

Create the cursor.

`fn create_cf_cursor_with_scan_mode( &mut self, cf: CfName, scan_mode: ScanMode ) -> Result<Cursor<S::Iter>>`[src]

Create the cursor with specified scan_mode, instead of inferring scan_mode from the config.
