Struct Error

unierr/error.go:78–87

Error is the unified error type for HTTP/gRPC transports. In grpc transports, Error can not only be constructed from a grpc status but also producing a native grpc status. In HTTP transports, Error can be encoded and decoded in json format. It also infers HTTP status code. The roundtrip conversion

// The roundtrip conversion makes Error suitable as a unification error model, on both client side and server side.
// Note the json format follows the JSONRPC standard.
type Error struct {
	err  error
	msg  string
	args []interface{}
	code codes.Code
	// Printer can ben used to achieve i18n. By default it is a text.BasePrinter.
	Printer contract.Printer
	// HttpStatusCodeFunc can overwrites the inferred HTTP status code from gRPC status.
	HttpStatusCodeFunc func(code codes.Code) int
}

// UnmarshalJSON implements json.Unmarshaler.
func (e *Error) UnmarshalJSON(bytes []byte) error {
