+/**
+ * The `Status` type defines a logical error model that is suitable for
+ * different
+ * 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.
