Module parameters 

Parameter binding and expression types for physical plans.

Parameters are compiled from named references (Expression::Parameter) to typed slots at plan-build time. At execution time, a ParameterFrame provides values by slot, avoiding string-based lookups in the hot path.

Structs

ParameterDesc

Describes one parameter in the plan’s parameter schema.

ParameterFrame

Runtime parameter values, bound at instance time.

ParameterSchema

The parameter schema of a physical plan.

ParameterSlot

A stable slot index for a query parameter within a physical plan.

SlotRef

Slot reference: refers to a column in the input chunk by position.

Enums

BoundExpression

A bound expression that has been resolved against the plan’s slot layout and parameter schema.
