Modules

bound_expr

Bound expression types — resolved, typed expressions ready for planning/execution.

coercion

Type coercion — implicit cast insertion for expression binding.

evaluator

Scalar evaluator — evaluate a BoundExpression against a single tuple.

function_registry

Function registry — scalar and aggregate function signatures.
