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][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. +type Status struct { + // The status code, which should be an enum value of + // [google.rpc.Code][google.rpc.Code]. + Code int32 `protobuf:"varint,1,opt,name=code,proto3" json:"code,omitempty"` + // A developer-facing error message, which should be in English.
