-        # in the package `google.rpc` that can be used for common error conditions.

-        # # Language mapping
-        #
-        # The `Status` message is the logical representation of the error model, but it
-        # is not necessarily the actual wire format. When the `Status` message is
-        # exposed in different client libraries and different wire protocols, it can be
-        # mapped differently. For example, it will likely be mapped to some exceptions
-        # in Java, but more likely mapped to some error codes in C.
-        #
-        # # Other uses
-        #
-        # The error model and the `Status` message can be used in a variety of
-        # environments, either with or without APIs, to provide a
-        # consistent developer experience across different environments.
-        #
-        # Example uses of this error model include:
-        #
-        # - Partial errors. If a service needs to return partial errors to the client,
-        #     it may embed the `Status` in the normal response to indicate the partial
-        #     errors.
-        #
-        # - Workflow errors. A typical workflow has multiple steps. Each step may
-        #     have a `Status` message for error reporting.
-        #
-        # - Batch operations. If a client uses batch request and batch response, the
-        #     `Status` message should be used directly inside batch response, one for
-        #     each error sub-response.
-        #
-        # - Asynchronous operations. If an API call embeds asynchronous operation
-        #     results in its response, the status of those operations should be
-        #     represented directly using the `Status` message.
-        #
