Trait datafusion::physical_optimizer::optimizer::PhysicalOptimizerRule [−][src]
pub trait PhysicalOptimizerRule {
fn optimize(
&self,
plan: Arc<dyn ExecutionPlan>,
config: &ExecutionConfig
) -> Result<Arc<dyn ExecutionPlan>>;
fn name(&self) -> &str;
}PhysicalOptimizerRule transforms one [‘ExecutionPlan’] into another which
computes the same results, but in a potentially more efficient
way.
Required methods
fn optimize(
&self,
plan: Arc<dyn ExecutionPlan>,
