akar_processor::physical::write_ops::physicalexplain

Struct PhysicalExplain

pub struct PhysicalExplain {
    pub inner_plan: String,
}

Expand description

Physical EXPLAIN operator — serializes a logical plan tree to a human-readable string and returns it as a single-row result.

Corresponds to C++ PlanPrinter::printPlanToOstream and mapExplain.

Fields§

§inner_plan: String

The inner logical operator tree to serialize.
