          #   Use BatchTranslateText for larger text.
          # @param target_language_code [String]

          #   text, set to one of the language codes listed in Language Support.
          # @param parent [String]
          #   Required. Project or location to make a call. Must refer to a caller's
          #   project.

          #   Format: `projects/{project-number-or-id}` or

          #   listed in Language Support. If the source language isn't specified, the API

          #   source language within the response.

          #   * General (built-in) models:
          #     `projects/{project-number-or-id}/locations/{location-id}/models/general/nmt`,
          #     `projects/{project-number-or-id}/locations/{location-id}/models/general/base`
          #
          #
          #   For global (non-regionalized) requests, use `location-id` `global`.
          #   For example,
          #   `projects/{project-number-or-id}/locations/global/models/general/nmt`.
          #
          #   If missing, the system decides which google base model to use.
          # @param glossary_config [Google::Cloud::Translate::V3::TranslateTextGlossaryConfig | Hash]
          #   Optional. Glossary to be applied. The glossary must be
          #   within the same region (have the same location-id) as the model, otherwise
          #   an INVALID_ARGUMENT (400) error is returned.
          #   A hash of the same form as `Google::Cloud::Translate::V3::TranslateTextGlossaryConfig`
          #   can also be provided.
          # @param labels [Hash{String => String}]
          #   Optional. The labels with user-defined metadata for the request.
          #
          #   Label keys and values can be no longer than 63 characters
          #   (Unicode codepoints), can only contain lowercase letters, numeric
          #   characters, underscores and dashes. International characters are allowed.

          #
          #   See https://cloud.google.com/translate/docs/labels for more information.
