Implementations

impl<S: Snapshot> PointGetterBuilder<S>

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

Initialize a new PointGetterBuilder.

pub fn multi(self, multi: bool) -> Self

Set whether or not to get multiple keys.

Defaults to true.

pub fn fill_cache(self, fill_cache: bool) -> Self

Set whether or not read operations should fill the cache.

Defaults to true.

pub fn omit_value(self, omit_value: bool) -> Self

Set whether values of the user key should be omitted. When omit_value is true, the length of returned value will be 0.

Previously this option is called key_only.

Defaults to false.

pub fn isolation_level(self, isolation_level: IsolationLevel) -> Self

Set the isolation level.

Defaults to IsolationLevel::Si.

pub fn bypass_locks(self, locks: TsSet) -> Self

Set a set to locks that the reading process can bypass.

Defaults to none.

pub fn check_has_newer_ts_data(self, enabled: bool) -> Self

Check whether there is data with newer ts. The result of met_newer_ts_data is Unknown if this option is not set.

Default is false.

pub fn build(self) -> Result<PointGetter<S>>

Build PointGetter from the current configuration.
