fn rewrite( &self, plan: LogicalPlan, _config: &dyn OptimizerConfig, ) -> Result<Transformed<LogicalPlan>>
Try to rewrite
plan to an optimized form, returning Transformed::yes
if the plan was rewritten and Transformed::no if it was not.Source§fn supports_rewrite(&self) -> bool

👎Deprecated since 47.0.0: This method is no longer used
Does this rule support rewriting owned plans (rather than by reference)?
