It works in concert with the Go source code generated -for .proto files by the protocol compiler. - -A summary of the properties of the protocol buffer interface -for a protocol buffer variable v: - - - Names are turned from camel_case to CamelCase for export. - - There are no methods on v to set fields; just treat - them as structure fields. - - There are getters that return a field's value if set, - and return the field's default value if unset. - The getters work even if the receiver is a nil message. - - The zero value for a struct is its correct initialization state. - All desired fields must be set before marshaling. - - A Reset() method will restore a protobuf struct to its zero state. - - Non-repeated fields are pointers to the values; nil means unset. - That is, optional or required field int32 f becomes F *int32. - - Repeated fields are slices. - - Helper functions are available to aid the setting of fields. - msg.Foo = proto.String("hello") // set field - - Constants are defined to hold the default values of all fields that - have them. They have the form Default_StructName_FieldName. - Because the getter methods handle defaulted values, - direct use of these constants should be rare. - - Enums are given type names and maps from names to values. - Enum values are prefixed by the enclosing message's name, or by the - enum's type name if it is a top-level enum. Enum types have a String - method, and a Enum method to assist in message construction. - - Nested messages, groups and enums have type names prefixed with the name of - the surrounding message type. - - Extensions are given descriptor names that start with E_, - followed by an underscore-delimited list of the nested messages - that contain it (if any) followed by the CamelCased name of the - extension field itself. HasExtension, ClearExtension, GetExtension - and SetExtension are functions for manipulating extensions. - - Oneof field sets are given a single field in their message, - with distinguished wrapper types for each possible field value. - - Marshal and Unmarshal are functions to encode and decode the wire format. - -When the .proto file specifies `syntax="proto3"`, there are some differences: - - - Non-repeated fields of non-message type are values instead of pointers. - - Enum types do not get an Enum method. - -The simplest way to describe this is to see an example. -Given file test.proto, containing - - package example;

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.

It is +// used by [gRPC](https://github.com/grpc). Each `Status` message contains +// three pieces of data: error code, error message, and error details. // -// 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. +// You can find out more about this error model and how to work with it in the +// [API Design Guide](https://cloud.google.com/apis/design/errors). type Status struct { - // The status code, which should be an enum value of [google.rpc.Code][google.rpc.Code]. + state protoimpl.MessageState + sizeCache protoimpl.SizeCache + unknownFields protoimpl.UnknownFields + + // The status code, which should be an enum value of + // [google.rpc.Code][google.rpc.Code].

The fractional +// seconds, which can go up to 9 digits (i.e. up to 1 nanosecond resolution), +// are optional. The "Z" suffix indicates the timezone ("UTC"); the timezone +// is required. A proto3 JSON serializer should always use UTC (as indicated by +// "Z") when printing the Timestamp type and a proto3 JSON parser should be +// able to accept both UTC and other timezones (as indicated by an offset). +// +// For example, "2017-01-15T01:30:15.01Z" encodes 15.01 seconds past +// 01:30 UTC on January 15, 2017. +// +// In JavaScript, one can convert a Date object to this format using the +// standard +// [toISOString()](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date/toISOString) +// method.
