        # @param [String] page_token
        #   Token identifying the page of results to return. If provided, use the

        # @param [Fixnum] page_size
        #   Maximum number of traces to return. If not specified or <= 0, the

        #   the root span)
        #   *   `start` (`start_time` field of the root span)
        #   Descending order can be specified by appending `desc` to the sort field
        #   (for example, `name desc`).
        #   Only one sort field is permitted.
        # @param [String] filter
        #   An optional filter for the request.
        #   Example:
        #   `version_label_key:a some_label:some_label_key`
        #   returns traces from version `a` and has `some_label` with `some_label_key`.

        #   collected from the application.
