Trait InfallibleRule 

trait InfallibleRule<C: ConventionMarker>:
    Send
    + Sync
    + Description {
    // Required method
    fn apply(&self, plan: PlanRef<C>) -> Option<PlanRef<C>>;
}

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

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.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
