Enum SlotType 

pub enum SlotType {
    Logical(LogicalType),
    NodeId,
    RelationalRowLocator,
}

The semantic value type or executor-private role assigned to one slot.

Query-visible values use the shared LogicalType. Physical identifiers and row locators remain explicit executor roles and cannot accidentally escape as logical schema types.

Variants

Logical(LogicalType)

NodeId

RelationalRowLocator
