impl LogicalCardinalityExt for LogicalPlanRef

fn max_one_row(&self) -> bool

Returns true if the plan node is guaranteed to yield at most one row.

fn row_count(&self) -> Option<usize>

Returns the number of rows the plan node is guaranteed to yield, if known exactly.

impl PlanCheckApplyEliminationExt for LogicalPlanRef

fn check_apply_elimination(&self) -> Result<(), RwError>

Checks if all LogicalApply nodes in the plan have been eliminated, that is, subqueries are successfully unnested.
