  // Returns the primary route along with optional alternate routes, given a set

  //
  // **NOTE:** This method requires that you specify a response field mask in
  // the input. You can provide the response field mask by using URL parameter
  // `$fields` or `fields`, or by using an HTTP/gRPC header `X-Goog-FieldMask`
  // (see the [available URL parameters and
  // headers](https://cloud.google.com/apis/docs/system-parameters). The value
  // is a comma separated list of field paths. See detailed documentation about
  // [how to construct the field
  // paths](https://github.com/protocolbuffers/protobuf/blob/master/src/google/protobuf/field_mask.proto).
  //
  // For example, in this method:
  //
  // * Field mask of all available fields (for manual inspection):
  //   `X-Goog-FieldMask: *`
  // * Field mask of Route-level duration, distance, and polyline (an example
  // production setup):
  //   `X-Goog-FieldMask:
  //   routes.duration,routes.distanceMeters,routes.polyline.encodedPolyline`
  //
  // Google discourage the use of the wildcard (`*`) response field mask, or
  // specifying the field mask at the top level (`routes`), because:
  //
  // * Selecting only the fields that you need helps our server save computation
  // cycles, allowing us to return the result to you with a lower latency.
  // * Selecting only the fields that you need
  // in your production job ensures stable latency performance. We might add
  // more response fields in the future, and those new fields might require
  // extra computation time. If you select all fields, or if you select all
  // fields at the top level, then you might experience performance degradation
  // because any new field we add will be automatically included in the
  // response.
  // * Selecting only the fields that you need results in a smaller response
  // size, and thus higher network throughput.
