+            # used by [gRPC](https://github.com/grpc). Each `Status` message contains

             #
-            # - 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` 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.
-            #
-            # - Logging. If some API errors are stored in logs, the message `Status` could
-            #     be used directly after any stripping needed for security/privacy reasons.
