  // `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);
  //     }
  //
  //  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 := ptypes.MarshalAny(foo)
  //      ...
  //      foo := &pb.Foo{}
  //      if err := ptypes.UnmarshalAny(any, 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. 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.
    //
    string type_url = 1;
  
    // Must be a valid serialized protocol buffer of the above specified type.
