// Status: 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` 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.
