Fields
context: EvalContextsrc: Srcconditions: Vec<RpnExpression>Implementations
impl BatchSelectionExecutor<Box<dyn BatchExecutor<StorageStats = ()>>>[src]
pub fn check_supported(descriptor: &Selection) -> Result<()>[src]
Checks whether this executor can be used.

fn handle_src_result(
&mut self,
src_result: &mut BatchExecuteResult
) -> Result<()>[src]
&mut self,
src_result: &mut BatchExecuteResult
) -> Result<()>
Accepts source result and mutates its logical_rows according to predicates.
When errors are returned, it means there are errors during the evaluation. Currently we treat this situation as “completely failed”.
