Fields

snapshot: S

fill_cache: bool

omit_value: bool

isolation_level: IsolationLevel

lower_bound: Option<Key>

[−] Expand description

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.

upper_bound: Option<Key>

hint_min_ts: Option<TimeStamp>

hint_max_ts: Option<TimeStamp>

ts: TimeStamp

desc: bool

bypass_locks: TsSet

check_has_newer_ts_data: bool

Implementations

impl<S: Snapshot> ScannerConfig<S>[−]

fn new(snapshot: S, ts: TimeStamp, desc: bool) -> Self

fn scan_mode(&self) -> ScanMode

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

Create the cursor.

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

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