+// `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 `@type` which contains the type URL. 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"
+//     }
+//
+message Any {
+    // 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. As of May 2023, there are no widely used type server
+    // implementations and no plans to implement one.
+    //
+    // Schemes other than `http`, `https` (or the empty scheme) might be
+    // used with implementation specific semantics.
+    //
+    string type_url = 1;
+
+    // Must be a valid serialized protocol buffer of the above specified type.
+    bytes value = 2;

+// A Timestamp represents a point in time independent of any time zone or local

+// nanosecond resolution. The count is relative to an epoch at UTC midnight on
+// January 1, 1970, in the proleptic Gregorian calendar which extends the
+// Gregorian calendar backwards to year one.
+//
+// All minutes are 60 seconds long. Leap seconds are "smeared" so that no leap
+// second table is needed for interpretation, using a [24-hour linear
+// smear](https://developers.google.com/time/smear).
+//
+// The range is from 0001-01-01T00:00:00Z to 9999-12-31T23:59:59.999999999Z. By
+// restricting to that range, we ensure that we can convert to and from [RFC
+// 3339](https://www.ietf.org/rfc/rfc3339.txt) date strings.
+//
+// # Examples
+//
+// Example 1: Compute Timestamp from POSIX `time()`.
+//
+//     Timestamp timestamp;
+//     timestamp.set_seconds(time(NULL));
+//     timestamp.set_nanos(0);
+//
+// Example 2: Compute Timestamp from POSIX `gettimeofday()`.
+//
+//     struct timeval tv;
+//     gettimeofday(&tv, NULL);
+//
+//     Timestamp timestamp;
+//     timestamp.set_seconds(tv.tv_sec);
+//     timestamp.set_nanos(tv.tv_usec * 1000);
+//
+// Example 3: Compute Timestamp from Win32 `GetSystemTimeAsFileTime()`.
+//
+//     FILETIME ft;
+//     GetSystemTimeAsFileTime(&ft);
+//     UINT64 ticks = (((UINT64)ft.dwHighDateTime) << 32) | ft.dwLowDateTime;
+//
+//     // A Windows tick is 100 nanoseconds. Windows epoch 1601-01-01T00:00:00Z
+//     // is 11644473600 seconds before Unix epoch 1970-01-01T00:00:00Z.
+//     Timestamp timestamp;
+//     timestamp.set_seconds((INT64) ((ticks / 10000000) - 11644473600LL));
+//     timestamp.set_nanos((INT32) ((ticks % 10000000) * 100));
+//
+// Example 4: Compute Timestamp from Java `System.currentTimeMillis()`.
+//
+//     long millis = System.currentTimeMillis();
+//
+//     Timestamp timestamp = Timestamp.newBuilder().setSeconds(millis / 1000)
+//         .setNanos((int) ((millis % 1000) * 1000000)).build();
+//
+// Example 5: Compute Timestamp from Java `Instant.now()`.
+//
+//     Instant now = Instant.now();
+//
+//     Timestamp timestamp =
+//         Timestamp.newBuilder().setSeconds(now.getEpochSecond())
+//             .setNanos(now.getNano()).build();
+//
+// Example 6: Compute Timestamp from current time in Python.
+//
+//     timestamp = Timestamp()
+//     timestamp.GetCurrentTime()
+//
+// # JSON Mapping
+//
+// In JSON format, the Timestamp type is encoded as a string in the
+// [RFC 3339](https://www.ietf.org/rfc/rfc3339.txt) format. That is, the
+// format is "{year}-{month}-{day}T{hour}:{min}:{sec}[.{frac_sec}]Z"
+// where {year} is always expressed using four digits while {month}, {day},
+// {hour}, {min}, and {sec} are zero-padded to two digits each. The fractional
+// seconds, which can go up to 9 digits (i.e. up to 1 nanosecond resolution),
+// are optional. The "Z" suffix indicates the timezone ("UTC"); the timezone
+// is required. A proto3 JSON serializer should always use UTC (as indicated by
+// "Z") when printing the Timestamp type and a proto3 JSON parser should be
+// able to accept both UTC and other timezones (as indicated by an offset).
+//
+// For example, "2017-01-15T01:30:15.01Z" encodes 15.01 seconds past
+// 01:30 UTC on January 15, 2017.
+//
+// In JavaScript, one can convert a Date object to this format using the
+// standard
+// [toISOString()](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date/toISOString)
+// method. In Python, a standard `datetime.datetime` object can be converted
+// to this format using
+// [`strftime`](https://docs.python.org/2/library/time.html#time.strftime) with
+// the time format spec '%Y-%m-%dT%H:%M:%S.%fZ'. Likewise, in Java, one can use
+// the Joda Time's [`ISODateTimeFormat.dateTime()`](
+// http://joda-time.sourceforge.net/apidocs/org/joda/time/format/ISODateTimeFormat.html#dateTime()
+// ) to obtain a formatter capable of generating timestamps in this format.
