Struct class final

Represents a JSON object.

An unordered key-value map, intending to perfectly capture the semantics of a JSON object. This enables parsing any arbitrary JSON payload as a message field in ProtoJSON format.

This follows RFC 8259 guidelines for interoperable JSON: notably this type cannot represent large Int64 values or NaN/Infinity numbers, since the JSON format generally does not support those values in its number type.

If you do not intend to parse arbitrary JSON into your message, a custom typed message should be preferred instead of using this type.
