Trait GenericPlanRef

pub trait GenericPlanRef: Eq + Hash {
    // Required methods
    fn id(&self) -> PlanNodeId;
    fn schema(&self) -> &Schema;
    fn stream_key(&self) -> Option<&[usize]>;
    fn functional_dependency(&self) -> &FunctionalDependencySet;
    fn ctx(&self) -> OptimizerContextRef;
}

Required Methods

fn id(&self) -> PlanNodeId

fn schema(&self) -> &Schema

fn stream_key(&self) -> Option<&[usize]>

fn functional_dependency(&self) -> &FunctionalDependencySet

fn ctx(&self) -> OptimizerContextRef

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
