                # programming environments, including REST APIs and RPC APIs. It is used by
                # [gRPC](https://github.com/grpc). The error model is designed to be:
                #
                # - Simple to use and understand for most users
                # - Flexible enough to meet unexpected needs
                #
                # # Overview
                #
                # The `Status` message contains three pieces of data: error code, error message,
                # and error details. The error code should be an enum value of
                # google.rpc.Code, but it may accept additional error codes if needed.  The
                # error message should be a developer-facing English message that helps
                # developers *understand* and *resolve* the error. If a localized user-facing
                # error message is needed, put the localized message in the error details or
                # localize it in the client. The optional error details may contain arbitrary
                # information about the error. There is a predefined set of error detail types
                # in the package `google.rpc` which 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 purpose.
                #
                # - 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.
                #
                # - Logging. If some API errors are stored in logs, the message `Status` could
                #     be used directly after any stripping needed for security/privacy reasons.

                  # user-facing error message should be localized and sent in the
