+/**
+ * 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 needsOverviewThe 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 mappingThe 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 usesThe 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:
