Trait OperatorTreeDriver 

pub trait OperatorTreeDriver {
    type Error;

    // Required method
    fn execute_node(
        &self,
        op: &OperatorTree,
    ) -> Result<OperatorOutput, Self::Error>;
}

Driver that knows how to execute an OperatorTree node. The engine implements this trait (it owns the per-operator dispatch, child execution, and the runtime context); the planner-side PlanExecutor only wraps root timing and stats collection.

Required Associated Types

type Error

Failure produced by the physical runtime while materialising a node or one of its descendants.

Required Methods

fn execute_node(&self, op: &OperatorTree) -> Result<OperatorOutput, Self::Error>

Dyn Compatibility

This trait is dyn compatible.

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