Module statement 

The NodedbStatement enum — one variant per DDL command.

Enums

GraphDirection

Traversal direction for graph DSL variants. Mirrors the engine’s own Direction enum so nodedb-sql has no dependency cycle with nodedb.

GraphProperties

The PROPERTIES clause of GRAPH INSERT EDGE. Captured in its source form so the pgwire handler — which already depends on a JSON serializer (sonic_rs) — can do the conversion to storage bytes without dragging JSON deps into nodedb-sql.

NodedbStatement

Typed representation of every NodeDB DDL statement.
