hash property

String? hash
getter/setter pair

Hash is this record's SHA-256 over its own canonical JSON with both hash fields cleared, folded with prevHash. Recomputing it from the row's other fields is what proves the row has not been edited.

Please note: This property should have been non-nullable! Since the specification file does not include a default value (using the "default:" property), however, the generated source code must fall back to having a nullable type. Consider adding a "default:" property in the specification file to hide this note.

Implementation

String? hash;
