Functions ¶

func Dief ¶

func Dief(err error, format string, values ...interface{})

func ErrorAs ¶

func ErrorAs(src error, target error) (error, bool)

Dive into wrapped errors from src until return an error that casts to the target error or such error is not found nolint:golint

func ExpandError ¶

func ExpandError(err error) interface{}

func LogErrorf ¶

func LogErrorf(err error, format string, args ...interface{})

func LogFatalf ¶

func LogFatalf(err error, format string, args ...interface{})

func MustSucceed ¶

func MustSucceed(err error, msg ...string)

func TryToUnwrap ¶

func TryToUnwrap(err error) error

Given an error, tries to unwrap it recursively until finds a "trivial" error which cannot be unwrapped anymore. It differs from errors.Unwrap() on returning the error itself in case it cannot be unwrapped, instead of nil

func UpdateErrorFromCall ¶

func UpdateErrorFromCall(f func() error, err *error)

func UpdateErrorFromCloser ¶

func UpdateErrorFromCloser(closer io.Closer, err *error)

UpdateErrorFromCloser is supposed to be used to close a io.Closer when a function exits, merging its error return into err, if any.

Types ¶

type Chainable ¶

type Chainable interface {
	Chain() ErrorChain
}

type Error ¶

type Error struct {
	Line     int
	Filename string
	Msg      string
	Err      error
}

func Wrap ¶

func Wrap(err error, args ...interface{}) *Error

Wrap an error adding more context such as filename and line where wrapping happened

func (*Error) Chain ¶

func (e *Error) Chain() ErrorChain

func (*Error) Error ¶

func (e *Error) Error() string

func (*Error) Unwrap ¶

func (e *Error) Unwrap() error

type ErrorChain ¶

type ErrorChain []error

nolint: errname

func BuildChain ¶

func BuildChain(outer, inner error) ErrorChain

func Chain ¶

func Chain(c Chainable) ErrorChain

Return a chain of errors, from top to bottom of the "stack"

func (ErrorChain) Error ¶

func (chain ErrorChain) Error() string

func (ErrorChain) JSON ¶

func (chain ErrorChain) JSON() []JsonErrorObject

type JsonErrorObject ¶

type JsonErrorObject struct {
	Error string `json:"error,omitempty"`
	File  string `json:"file,omitempty"`
	Line  int    `json:"line,omitempty"`
}
