+/**
+ * `Any` contains an arbitrary serialized protocol buffer message along with a
+ * URL that describes the type of the serialized message.
+ * Protobuf library provides support to pack/unpack Any values in the form
+ * of utility functions or additional generated methods of the Any type.
+ * Example 1: Pack and unpack a message in C++.
+ *     Foo foo = ...;
+ *     Any any;
+ *     any.PackFrom(foo);
+ *     ...
+ *     if (any.UnpackTo(&foo)) {
+ *       ...
+ *     }
+ * Example 2: Pack and unpack a message in Java.
+ *     Foo foo = ...;
+ *     Any any = Any.pack(foo);
+ *     ...
+ *     if (any.is(Foo.class)) {
+ *       foo = any.unpack(Foo.class);
+ *     }
+ *     // or ...
+ *     if (any.isSameTypeAs(Foo.getDefaultInstance())) {
+ *       foo = any.unpack(Foo.getDefaultInstance());
+ *     }
+ * Example 3: Pack and unpack a message in Python.
+ *     foo = Foo(...)
+ *     any = Any()
+ *     any.Pack(foo)
+ *     ...
+ *     if any.Is(Foo.DESCRIPTOR):
+ *       any.Unpack(foo)
+ *       ...
+ * Example 4: Pack and unpack a message in Go
+ *      foo := &pb.Foo{...}
+ *      any, err := anypb.New(foo)
+ *      if err != nil {
+ *        ...
+ *      }
+ *      ...
+ *      foo := &pb.Foo{}
+ *      if err := any.UnmarshalTo(foo); err != nil {
+ *        ...
+ *      }
+ * The pack methods provided by protobuf library will by default use
+ * 'type.googleapis.com/full.type.name' as the type URL and the unpack
+ * methods only use the fully qualified type name after the last '/'
+ * in the type URL, for example "foo.bar.com/x/y.z" will yield type
+ * name "y.z".
+ * JSON
+ * The JSON representation of an `Any` value uses the regular
+ * representation of the deserialized, embedded message, with an
+ * additional field `&#64;type` which contains the type URL. Example:
+ *     package google.profile;
+ *     message Person {
+ *       string first_name = 1;
+ *       string last_name = 2;
+ *     }
+ *     {
+ *       "&#64;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 `&#64;type`
+ * field. Example (for message [google.protobuf.Duration][]):
+ *     {
+ *       "&#64;type": "type.googleapis.com/google.protobuf.Duration",
+ *       "value": "1.212s"
+ *     }
+ *
+ * Generated from protobuf message <code>google.protobuf.Any</code>

+ * A Duration represents a signed, fixed-length span of time represented

+ * or "month". It is related to Timestamp in that the difference between
+ * two Timestamp values is a Duration and it can be added or subtracted
+ * from a Timestamp. Range is approximately +-10,000 years.
+ * # Examples
+ * Example 1: Compute Duration from two Timestamps in pseudo code.
+ *     Timestamp start = ...;
+ *     Timestamp end = ...;
+ *     Duration duration = ...;
+ *     duration.seconds = end.seconds - start.seconds;

+ *       duration.seconds -= 1;
+ *       duration.nanos += 1000000000;
+ *     }
+ * Example 2: Compute Timestamp from Timestamp + Duration in pseudo code.
+ *     Timestamp start = ...;
+ *     Duration duration = ...;
+ *     Timestamp end = ...;
+ *     end.seconds = start.seconds + duration.seconds;
+ *     end.nanos = start.nanos + duration.nanos;

+ * In JSON format, the Duration type is encoded as a string rather than an
+ * object, where the string ends in the suffix "s" (indicating seconds) and
+ * is preceded by the number of seconds, with nanoseconds expressed as
+ * fractional seconds. For example, 3 seconds with 0 nanoseconds should be

+/**
+ * `FieldMask` represents a set of symbolic field paths, for example:
+ *     paths: "f.a"
+ *     paths: "f.b.d"
+ * Here `f` represents a field in some root message, `a` and `b`
+ * fields in the message found in `f`, and `d` a field found in the
+ * message in `f.b`.
+ * Field masks are used to specify a subset of fields that should be
+ * returned by a get operation or modified by an update operation.
+ * Field masks also have a custom JSON encoding (see below).
+ * # Field Masks in Projections
+ * When used in the context of a projection, a response message or
+ * sub-message is filtered by the API to only contain those fields as
+ * specified in the mask. For example, if the mask in the previous
+ * example is applied to a response message as follows:
+ *     f {
+ *       a : 22
+ *       b {
+ *         d : 1
+ *         x : 2
+ *       }
+ *       y : 13
+ *     }
+ *     z: 8
+ * The result will not contain specific values for fields x,y and z
+ * (their value will be set to the default, and omitted in proto text
+ * output):
+ *     f {
+ *       a : 22
+ *       b {
+ *         d : 1
+ *       }
+ *     }
+ * A repeated field is not allowed except at the last position of a
+ * paths string.
+ * If a FieldMask object is not present in a get operation, the
+ * operation applies to all fields (as if a FieldMask of all fields
+ * had been specified).
+ * Note that a field mask does not necessarily apply to the
+ * top-level response message. In case of a REST get operation, the
+ * field mask applies directly to the response, but in case of a REST
+ * list operation, the mask instead applies to each individual message
+ * in the returned resource list. In case of a REST custom method,
+ * other definitions may be used. Where the mask applies will be
+ * clearly documented together with its declaration in the API.  In
+ * any case, the effect on the returned resource/resources is required
+ * behavior for APIs.
+ * # Field Masks in Update Operations
+ * A field mask in update operations specifies which fields of the
+ * targeted resource are going to be updated. The API is required
+ * to only change the values of the fields as specified in the mask
+ * and leave the others untouched. If a resource is passed in to
+ * describe the updated values, the API ignores the values of all
+ * fields not covered by the mask.
+ * If a repeated field is specified for an update operation, new values will
+ * be appended to the existing repeated field in the target resource. Note that
+ * a repeated field is only allowed in the last position of a `paths` string.
+ * If a sub-message is specified in the last position of the field mask for an
+ * update operation, then new value will be merged into the existing sub-message
+ * in the target resource.
+ * For example, given the target message:
+ *     f {
+ *       b {
+ *         d: 1
+ *         x: 2
+ *       }
+ *       c: [1]
+ *     }
+ * And an update message:
+ *     f {
+ *       b {
+ *         d: 10
+ *       }
+ *       c: [2]
+ *     }
+ * then if the field mask is:
+ *  paths: ["f.b", "f.c"]
+ * then the result will be:
+ *     f {
+ *       b {
+ *         d: 10
+ *         x: 2
+ *       }
+ *       c: [1, 2]
+ *     }
+ * An implementation may provide options to override this default behavior for
+ * repeated and message fields.
+ * In order to reset a field's value to the default, the field must
+ * be in the mask and set to the default value in the provided resource.
+ * Hence, in order to reset all fields of a resource, provide a default
+ * instance of the resource and set all fields in the mask, or do
+ * not provide a mask as described below.
+ * If a field mask is not present on update, the operation applies to
+ * all fields (as if a field mask of all fields has been specified).
+ * Note that in the presence of schema evolution, this may mean that
+ * fields the client does not know and has therefore not filled into
+ * the request will be reset to their default. If this is unwanted
+ * behavior, a specific service may require a client to always specify
+ * a field mask, producing an error if not.
+ * As with get operations, the location of the resource which
+ * describes the updated values in the request message depends on the
+ * operation kind. In any case, the effect of the field mask is
+ * required to be honored by the API.
+ * ## Considerations for HTTP REST
+ * The HTTP kind of an update operation which uses a field mask must
+ * be set to PATCH instead of PUT in order to satisfy HTTP semantics
+ * (PUT must only be used for full updates).
+ * # JSON Encoding of Field Masks
+ * In JSON, a field mask is encoded as a single string where paths are
+ * separated by a comma. Fields name in each path are converted
+ * to/from lower-camel naming conventions.
+ * As an example, consider the following message declarations:
+ *     message Profile {
+ *       User user = 1;
+ *       Photo photo = 2;
+ *     }
+ *     message User {
+ *       string display_name = 1;
+ *       string address = 2;
+ *     }
+ * In proto a field mask for `Profile` may look as such:
+ *     mask {
+ *       paths: "user.display_name"
+ *       paths: "photo"
+ *     }
+ * In JSON, the same mask is represented as below:
+ *     {
+ *       mask: "user.displayName,photo"
+ *     }
+ * # Field Masks and Oneof Fields
+ * Field masks treat fields in oneofs just as regular fields. Consider the
+ * following message:
+ *     message SampleMessage {
+ *       oneof test_oneof {
+ *         string name = 4;
+ *         SubMessage sub_message = 9;
+ *       }
+ *     }
+ * The field mask can be:
+ *     mask {
+ *       paths: "name"
+ *     }
+ * Or:
+ *     mask {
+ *       paths: "sub_message"
+ *     }
+ * Note that oneof type names ("test_oneof" in this case) cannot be used in
+ * paths.
+ * ## Field Mask Verification
+ * The implementation of any API method which has a FieldMask type field in the
+ * request should verify the included field paths, and return an
+ * `INVALID_ARGUMENT` error if any path is unmappable.
