-// `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 whose content describes the type of the
-  // serialized protocol buffer message.
-  //
-  // For URLs which use the scheme `http`, `https`, or no scheme, the
-  // following restrictions and interpretations apply:
-  //
-  // * If no scheme is provided, `https` is assumed.
-  // * 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).
-  // * 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.)
-  //
-  // 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.

-//         option (google.api.http).get = "/v2/{resource=**}";
-//       }
-//     }
-//
-// Example of a mixin configuration:
-//
-//     apis:
-//     - name: google.storage.v2.Storage
-//       mixins:
-//       - name: google.acl.v1.AccessControl
-//
-// The mixin construct implies that all methods in `AccessControl` are
-// also declared with same name and request/response types in
-// `Storage`. A documentation generator or annotation processor will
-// see the effective `Storage.GetAcl` method after inherting
-// documentation and annotations as follows:
-//
-//     service Storage {
-//       // Get the underlying ACL object.
-//       rpc GetAcl(GetAclRequest) returns (Acl) {
-//         option (google.api.http).get = "/v2/{resource=**}:getAcl";
-//       }
-//       ...
-//     }
-//
-// Note how the version in the path pattern changed from `v1` to `v2`.
-//
-// If the `root` field in the mixin is specified, it should be a
-// relative path under which inherited HTTP paths are placed. Example:
-//
-//     apis:
-//     - name: google.storage.v2.Storage
-//       mixins:
-//       - name: google.acl.v1.AccessControl
-//         root: acls
-//
-// This implies the following inherited HTTP annotation:
-//
-//     service Storage {
-//       // Get the underlying ACL object.
-//       rpc GetAcl(GetAclRequest) returns (Acl) {
-//         option (google.api.http).get = "/v2/acls/{resource=**}:getAcl";
-//       }
-//       ...
-//     }

-// 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.

-  //   logically enclosed in a single code segment.  For example, an entire
-  //   extend block (possibly containing multiple extension definitions) will
-  //   have an outer location whose path refers to the "extensions" repeated
-  //   field without an index.
-  // - Multiple locations may have the same path.  This happens when a single
-  //   logical declaration is spread out across multiple places.  The most
-  //   obvious example is the "extend" block again -- there may be multiple

-  //   the block.
-  // - Just because a location's span is a subset of some other location's span
-  //   does not mean that it is a descendent.  For example, a "group" defines
-  //   both a type and a field in a single declaration.  Thus, the locations
-  //   corresponding to the type and field and their components will overlap.

-// `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, the existing
-// repeated values in the target resource will be overwritten by the new values.
-// 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 the existing sub-message in the target resource is
-// overwritten. Given the target message:
-//
-//     f {
-//       b {
-//         d : 1
-//         x : 2
-//       }
-//       c : 1
-//     }
-//
-// And an update message:
-//
-//     f {
-//       b {
-//         d : 10
-//       }
-//     }
-//
-// then if the field mask is:
-//
-//  paths: "f.b"
-//
-// then the result will be:
-//
-//     f {
-//       b {
-//         d : 10
-//       }
-//       c : 1
-//     }
-//
-// However, if the update mask was:
-//
-//  paths: "f.b.d"
-//
-// then the result would be:
-//
-//     f {
-//       b {
-//         d : 10
-//         x : 2
-//       }
-//       c : 1
-//     }
-//
-// 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.
-message FieldMask {
-  // The set of field mask paths.

-// A Timestamp represents a point in time independent of any time zone
-// or calendar, represented as seconds and fractions of seconds at
-// nanosecond resolution in UTC Epoch time. It is encoded using the
-// Proleptic Gregorian Calendar which extends the Gregorian calendar
-// backwards to year one. It is encoded assuming all minutes are 60
-// seconds long, i.e. leap seconds are "smeared" so that no leap second
-// table is needed for interpretation. 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 date strings.
-// See [https://www.ietf.org/rfc/rfc3339.txt](https://www.ietf.org/rfc/rfc3339.txt).
-//
-// # 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 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, though only UTC (as indicated by "Z") is presently supported.
-//
-// 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.
-//
