Module scalar 

AST-independent scalar physical IR shared by the planner and executors.

Structs

ScalarEvalContext

ScalarOrder

ScalarWindowFrame

ScalarWindowSpec

SubqueryResult

Pull-based scalar-subquery result. Scalar, EXISTS, and IN consumers never need to materialize the complete child relation: they respectively inspect at most two rows, one row, or one row at a time.

Enums

ScalarExpr

ScalarFrameBound

Traits

ScalarSubqueryRunner

Runtime callback for query children referenced by SubqueryId. The planner owns the actual query-plan arena; execution only needs this stable slot interface.

Functions

eval_call_arguments

eval_scalar

Evaluate the physical scalar tree directly. No parser expression is reconstructed at this boundary.

Type Aliases

SubqueryId

Index into the query children owned by the enclosing expression plan.
