Types

type Chain

type Chain []error

Chain - цепочка ошибок

func (Chain) As

func (ch Chain) As(target interface{}) bool

func (Chain) Error

func (ch Chain) Error() string

func (Chain) Is

func (ch Chain) Is(err error) bool

type Const

type Const string

Const тип используемый для константных ошибок, позволяет избегать возможных мутаций значений ошибок.

func (Const) Error

func (e Const) Error() string

type CustomError
