+// APIs](https://github.com/googleapis/googleapis),
+// [Cloud Endpoints](https://cloud.google.com/endpoints), [gRPC
+// Gateway](https://github.com/grpc-ecosystem/grpc-gateway),
+// and [Envoy](https://github.com/envoyproxy/envoy) proxy support this feature
+// and use it for large scale production services.
+//
+// `HttpRule` defines the schema of the gRPC/REST mapping. The mapping specifies
+// how different portions of the gRPC request message are mapped to the URL
+// path, URL query parameters, and HTTP request body. It also controls how the
+// gRPC response message is mapped to the HTTP response body. `HttpRule` is
+// typically specified as an `google.api.http` annotation on the gRPC method.
+//
+// Each mapping specifies a URL path template and an HTTP method. The path
+// template may refer to one or more fields in the gRPC request message, as long
+// as each field is a non-repeated field with a primitive (non-message) type.
+// The path template controls how fields of the request message are mapped to
+// the URL path.
+//
+// Example:
+//
+//     service Messaging {
+//       rpc GetMessage(GetMessageRequest) returns (Message) {
+//         option (google.api.http) = {
+//             get: "/v1/{name=messages/*}"
+//         };
+//       }
+//     }
+//     message GetMessageRequest {
+//       string name = 1; // Mapped to URL path.
+//     }
+//     message Message {
+//       string text = 1; // The resource content.
+//     }
+//
+// This enables an HTTP REST to gRPC mapping as below:
+//
+// HTTP | gRPC
+// -----|-----
+// `GET /v1/messages/123456`  | `GetMessage(name: "messages/123456")`
+//
+// Any fields in the request message which are not bound by the path template
+// automatically become HTTP query parameters if there is no HTTP request body.
+// For example:
+//
+//     service Messaging {
+//       rpc GetMessage(GetMessageRequest) returns (Message) {
+//         option (google.api.http) = {
+//             get:"/v1/messages/{message_id}"
+//         };
+//       }
+//     }
+//     message GetMessageRequest {
+//       message SubMessage {
+//         string subfield = 1;
+//       }
+//       string message_id = 1; // Mapped to URL path.
+//       int64 revision = 2;    // Mapped to URL query parameter `revision`.
+//       SubMessage sub = 3;    // Mapped to URL query parameter `sub.subfield`.
+//     }
+//
+// This enables a HTTP JSON to RPC mapping as below:
+//
+// HTTP | gRPC
+// -----|-----
+// `GET /v1/messages/123456?revision=2&sub.subfield=foo` |
+// `GetMessage(message_id: "123456" revision: 2 sub: SubMessage(subfield:
+// "foo"))`
+//
+// Note that fields which are mapped to URL query parameters must have a
+// primitive type or a repeated primitive type or a non-repeated message type.
+// In the case of a repeated type, the parameter can be repeated in the URL
+// as `...?param=A&param=B`. In the case of a message type, each field of the
+// message is mapped to a separate parameter, such as
+// `...?foo.a=A&foo.b=B&foo.c=C`.
+//
+// For HTTP methods that allow a request body, the `body` field
+// specifies the mapping. Consider a REST update method on the
+// message resource collection:
+//
+//     service Messaging {
+//       rpc UpdateMessage(UpdateMessageRequest) returns (Message) {
+//         option (google.api.http) = {
+//           patch: "/v1/messages/{message_id}"
+//           body: "message"
+//         };
+//       }
+//     }
+//     message UpdateMessageRequest {
+//       string message_id = 1; // mapped to the URL
+//       Message message = 2;   // mapped to the body
+//     }
+//
+// The following HTTP JSON to RPC mapping is enabled, where the
+// representation of the JSON in the request body is determined by
+// protos JSON encoding:
+//
+// HTTP | gRPC
+// -----|-----
+// `PATCH /v1/messages/123456 { "text": "Hi!" }` | `UpdateMessage(message_id:
+// "123456" message { text: "Hi!" })`
+//
+// The special name `*` can be used in the body mapping to define that
+// every field not bound by the path template should be mapped to the
+// request body.  This enables the following alternative definition of
+// the update method:
+//
+//     service Messaging {
+//       rpc UpdateMessage(Message) returns (Message) {
+//         option (google.api.http) = {
+//           patch: "/v1/messages/{message_id}"
+//           body: "*"
+//         };
+//       }
+//     }
+//     message Message {
+//       string message_id = 1;
+//       string text = 2;
+//     }
+//
+//
+// The following HTTP JSON to RPC mapping is enabled:
+//
+// HTTP | gRPC
+// -----|-----
+// `PATCH /v1/messages/123456 { "text": "Hi!" }` | `UpdateMessage(message_id:
+// "123456" text: "Hi!")`
+//
+// Note that when using `*` in the body mapping, it is not possible to
+// have HTTP parameters, as all fields not bound by the path end in
+// the body. This makes this option more rarely used in practice when
+// defining REST APIs. The common usage of `*` is in custom methods
+// which don't use the URL at all for transferring data.
+//
+// It is possible to define multiple HTTP methods for one RPC by using
+// the `additional_bindings` option. Example:
+//
+//     service Messaging {
+//       rpc GetMessage(GetMessageRequest) returns (Message) {
+//         option (google.api.http) = {
+//           get: "/v1/messages/{message_id}"
+//           additional_bindings {
+//             get: "/v1/users/{user_id}/messages/{message_id}"
+//           }
+//         };
+//       }
+//     }
+//     message GetMessageRequest {
+//       string message_id = 1;
+//       string user_id = 2;
+//     }
+//
+// This enables the following two alternative HTTP JSON to RPC mappings:
+//
+// HTTP | gRPC
+// -----|-----
+// `GET /v1/messages/123456` | `GetMessage(message_id: "123456")`
+// `GET /v1/users/me/messages/123456` | `GetMessage(user_id: "me" message_id:
+// "123456")`
+//
+// ## Rules for HTTP mapping
+//
+// 1. Leaf request fields (recursive expansion nested messages in the request
+//    message) are classified into three categories:
+//    - Fields referred by the path template. They are passed via the URL path.
+//    - Fields referred by the [HttpRule.body][google.api.HttpRule.body]. They are passed via the HTTP
+//      request body.
+//    - All other fields are passed via the URL query parameters, and the
+//      parameter name is the field path in the request message. A repeated
+//      field can be represented as multiple query parameters under the same
+//      name.
+//  2. If [HttpRule.body][google.api.HttpRule.body] is "*", there is no URL query parameter, all fields
+//     are passed via URL path and HTTP request body.
+//  3. If [HttpRule.body][google.api.HttpRule.body] is omitted, there is no HTTP request body, all
+//     fields are passed via URL path and URL query parameters.
+//
+// ### Path template syntax
+//
+//     Template = "/" Segments [ Verb ] ;
+//     Segments = Segment { "/" Segment } ;
+//     Segment  = "*" | "**" | LITERAL | Variable ;
+//     Variable = "{" FieldPath [ "=" Segments ] "}" ;
+//     FieldPath = IDENT { "." IDENT } ;
+//     Verb     = ":" LITERAL ;
+//
+// The syntax `*` matches a single URL path segment. The syntax `**` matches
+// zero or more URL path segments, which must be the last part of the URL path
+// except the `Verb`.
+//
+// The syntax `Variable` matches part of the URL path as specified by its
+// template. A variable template must not contain other variables. If a variable
+// matches a single path segment, its template may be omitted, e.g. `{var}`
+// is equivalent to `{var=*}`.
+//
+// The syntax `LITERAL` matches literal text in the URL path. If the `LITERAL`
+// contains any reserved character, such characters should be percent-encoded
+// before the matching.
+//
+// If a variable contains exactly one path segment, such as `"{var}"` or
+// `"{var=*}"`, when such a variable is expanded into a URL path on the client
+// side, all characters except `[-_.~0-9a-zA-Z]` are percent-encoded. The
+// server side does the reverse decoding. Such variables show up in the
+// [Discovery
+// Document](https://developers.google.com/discovery/v1/reference/apis) as
+// `{var}`.
+//
+// If a variable contains multiple path segments, such as `"{var=foo/*}"`
+// or `"{var=**}"`, when such a variable is expanded into a URL path on the
+// client side, all characters except `[-_.~/0-9a-zA-Z]` are percent-encoded.
+// The server side does the reverse decoding, except "%2F" and "%2f" are left
+// unchanged. Such variables show up in the
+// [Discovery
+// Document](https://developers.google.com/discovery/v1/reference/apis) as
+// `{+var}`.
+//
+// ## Using gRPC API Service Configuration
+//
+// gRPC API Service Configuration (service config) is a configuration language
+// for configuring a gRPC service to become a user-facing product. The
+// service config is simply the YAML representation of the `google.api.Service`
+// proto message.
+//
+// As an alternative to annotating your proto file, you can configure gRPC
+// transcoding in your service config YAML files. You do this by specifying a
+// `HttpRule` that maps the gRPC method to a REST endpoint, achieving the same
+// effect as the proto annotation. This can be particularly useful if you
+// have a proto that is reused in multiple services. Note that any transcoding
+// specified in the service config will override any matching transcoding
+// configuration in the proto.
+//
+// Example:
+//
+//     http:
+//       rules:
+//         # Selects a gRPC method and applies HttpRule to it.
+//         - selector: example.v1.Messaging.GetMessage
+//           get: /v1/messages/{message_id}/{sub.subfield}
+//
+// ## Special notes
+//
+// When gRPC Transcoding is used to map a gRPC to JSON REST endpoints, the
+// proto to JSON conversion must follow the [proto3
+// specification](https://developers.google.com/protocol-buffers/docs/proto3#json).
+//
+// While the single segment variable follows the semantics of
+// [RFC 6570](https://tools.ietf.org/html/rfc6570) Section 3.2.2 Simple String
+// Expansion, the multi segment variable **does not** follow RFC 6570 Section
+// 3.2.3 Reserved Expansion. The reason is that the Reserved Expansion
+// does not expand special characters like `?` and `#`, which would lead
+// to invalid URLs. As the result, gRPC Transcoding uses a custom encoding
+// for multi segment variables.
+//
+// The path variables **must not** refer to any repeated or mapped field,
+// because client libraries are not capable of handling such variable expansion.
+//
+// The path variables **must not** capture the leading "/" character. The reason
+// is that the most common use case "{var}" does not capture the leading "/"
+// character. For consistency, all path variables must share the same behavior.
+//
+// Repeated message fields must not be mapped to URL query parameters, because
+// no client library can support such complicated mapping.
+//
+// If an API needs to use a JSON array for request or response body, it can map
+// the request or response body to a repeated field. However, some gRPC
+// Transcoding implementations may not support this feature.

+// 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;

+//       "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.

+// Note how the version in the path pattern changed from `v1` to `v2`.

+// 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.

+// `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.
+message FieldMask {
+  // The set of field mask paths.
+  repeated string paths = 1;

+// A Timestamp represents a point in time independent of any time zone or local
+// calendar, encoded as a count of seconds and fractions of seconds at
+// 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://www.joda.org/joda-time/apidocs/org/joda/time/format/ISODateTimeFormat.html#dateTime%2D%2D
+// ) to obtain a formatter capable of generating timestamps in this format.
