+// `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 duplicated or unmappable.
