Example: * * package google.profile; * message Person { * string first_name = 1; * string last_name = 2; * } * * { * "@type": "type.googleapis.com/google.profile.Person", * "firstName": <string>, * "lastName": <string> * } * * If the embedded message type is well-known and has a custom JSON * representation, that representation will be embedded adding a field * `value` which holds the custom JSON in addition to the `@type` * field. Example (for message google.protobuf.Duration): * * { * "@type": "type.googleapis.com/google.protobuf.Duration", * "value": "1.212s" * } * * @property {string} typeUrl * A URL/resource name that uniquely identifies the type of the serialized * protocol buffer message. This string must contain at least * one "/" character. The last segment of the URL's path must represent * the fully qualified name of the type (as in * `path/google.protobuf.Duration`). The name should be in a canonical form * (e.g., leading "." is not accepted). * * In practice, teams usually precompile into the binary all types that they * expect it to use in the context of Any. However, for URLs which use the * scheme `http`, `https`, or no scheme, one can optionally set up a type * server that maps type URLs to message definitions as follows: * * * If no scheme is provided, `https` is assumed. * * An HTTP GET on the URL must yield a google.protobuf.Type * value in binary format, or produce an error. * * Applications are allowed to cache lookup results based on the * URL, or have them precompiled into a binary to avoid any * lookup. Therefore, binary compatibility needs to be preserved * on changes to types. (Use versioned type names to manage * breaking changes.) * * Note: this functionality is not currently available in the official * protobuf release, and it is not used for type URLs beginning with * type.googleapis.com. * * Schemes other than `http`, `https` (or the empty scheme) might be * used with implementation specific semantics. * * @property {Buffer} value * Must be a valid serialized protocol buffer of the above specified type. * * @typedef Any * @memberof google.protobuf * @see [google.protobuf.Any definition in proto format]{@link https://github.com/google/protobuf/blob/master/src/google/protobuf/any.proto} */ const Any = { // This is for documentation.
