Types

type Causer

type Causer interface {
	Cause() error
}

type CodedError

type CodedError struct {
	Code    int32  `json:"code"`
	Message string `json:"message,omitempty"`

}

func Coded

func Coded(code int32, msg string, detail ...string) *CodedError

Coded return an coded error.

func (*CodedError) Error

func (e *CodedError) Error() string

type ListError

type ListError []error

func List

func List(errs ...error) ListError

List returns an error which wraps multiple errors
