Required methods

fn get(&self, key: &Key, statistics: &mut Statistics) -> Result<Option<Value>>[src]

Fetch the provided key.

fn incremental_get(&mut self, key: &Key) -> Result<Option<Value>>[src]

Re-use last cursor to incrementally (if possible) fetch the provided key.

fn incremental_get_take_statistics(&mut self) -> Statistics[src]

Take the statistics. Currently only available for incremental_get.

fn incremental_get_met_newer_ts_data(&self) -> NewerTsCheckState[src]

Whether there was data > ts during previous incremental gets.

fn batch_get(
    &self,
    keys: &[Key],
    statistics: &mut Statistics
) -> Result<Vec<Result<Option<Value>>>>[src]

Fetch the provided set of keys.

fn scanner(
    &self,
    desc: bool,
    key_only: bool,
    check_has_newer_ts_data: bool,
    lower_bound: Option<Key>,
    upper_bound: Option<Key>
) -> Result<Self::Scanner>[src]

Retrieve a scanner over the bounds.
