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.

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.
