    // Required method
    fn apply(&self, plan: PlanRef<C>) -> Option<PlanRef<C>>;
}
Expand description

An one-to-one transform for the PlanNode.

It’s a convenient trait to implement FallibleRule, thus made available only within this module.

Required Methods§

Source

fn apply(&self, plan: PlanRef<C>) -> Option<PlanRef<C>>

Apply the rule to the plan node.

  • Returns Some if the apply is successful.
  • Returns None if it’s not applicable. The optimizer may try other rules.
