// ===================================================================
// Options

// Each of the definitions above may have "options" attached.  These are
// just annotations which may cause code to be generated slightly differently
// or may contain hints for code that manipulates protocol messages.
//
// Clients may define custom options as extensions of the *Options messages.
// These extensions may not yet be known at parsing time, so the parser cannot
// store the values in them.  Instead it stores them in a field in the *Options
// message called uninterpreted_option. This field must have the same name
// across all *Options messages. We then use this field to populate the
// extensions when we build a descriptor, at which point all protos have been
// parsed and so all extensions are known.
//
// Extension numbers for custom options may be chosen as follows:
// * For options which will only be used within a single application or
//   organization, or for experimental options, use field numbers 50000
//   through 99999.  It is up to you to ensure that you do not use the
//   same number for multiple options.
// * For options which will be published and used publicly by multiple
//   independent entities, e-mail protobuf-global-extension-registry@google.com
//   to reserve extension numbers. Simply provide your project name (e.g.
//   Objective-C plugin) and your project website (if available) -- there's no
//   need to explain how you intend to use them. Usually you only need one
//   extension number. You can declare multiple options with only one extension
//   number by putting them in a sub-message. See the Custom Options section of
//   the docs for examples:
//   <https://developers.google.com/protocol-buffers/docs/proto#options>
//   If this turns out to be popular, a web service will be set up
//   to automatically assign option numbers.

///        ...

/// The pack methods provided by protobuf library will by default use

/// 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"
///     }
///

/// 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.

///
///     Timestamp timestamp;
///     timestamp.set_seconds(tv.tv_sec);

///     Timestamp timestamp;

///     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();

///     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://www.joda.org/joda-time/apidocs/org/joda/time/format/ISODateTimeFormat.html#dateTime%2D%2D>
