Trait BatchPlanNodeMetadata 

pub trait BatchPlanNodeMetadata: PhysicalPlanRef {
    // Required method
    fn order(&self) -> &Order;

    // Provided method
    fn orders(&self) -> Vec<Order> { ... }
}

A subtrait of PhysicalPlanRef for batch plans.

Due to the lack of refactoring, all plan nodes currently implement this trait through super::PlanBase. One may still use this trait as a bound for accessing a batch plan, in contrast to GenericPlanRef or PhysicalPlanRef.

Required Methods

fn order(&self) -> &Order

Provided Methods

fn orders(&self) -> Vec<Order>

Dyn Compatibility

This trait is not dyn compatible.

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