The JSON representation of the object's Move struct content.
Warning: The exact shape and field names of this data may vary between different
API implementations (JSON-RPC vs gRPC or GraphQL). For consistent data across APIs use
the content field and parse the BCS data directly.
Full BCS-encoded object envelope — parse with bcs.Object not a struct parser.
BCS-encoded Move struct content — pass to generated BCS type parsers.
