Detailed Description

Serializable data model for QueryGraph diagnostic dumps.

These structures form the in-memory representation returned by graph::dump(). Their serialized layout is described in doc/dump-file-format.md.

Definition in file graphdata.hpp.

tsig

using rpnx::querygraph::tsig = std::array< std::byte, 16 >

Fixed-size RPNXSerialization type-signature digest.

status

enum class rpnx::querygraph::status : std::uint8_t

strong

Terminal or in-progress state recorded for a dumped result.

• pending: the query or subquery has not reached a terminal state.
• completed: evaluation completed with a value.
• canonical_error: evaluation failed with a registered, serializable exception.
• unexpected_exception: evaluation failed with an exception that cannot be serialized canonically.
