Functions

func IsSystemError

func IsSystemError(err error) bool

IsSystemError will unwrap err to the innermost error value and return whether it is a SystemError.

func IsUserError

func IsUserError(err error) bool

IsUserError will unwrap err to the innermost error value and return whether it is a UserError.

func SystemError

func SystemError(err error) error

SystemError annotates err in such a way that IsSystemError() can be used further up in the callstack. If err is a wrapped error, the root error will be unwrapped, annotated and rewrapped instead. The root error stack trace is preserved but any middle ones are lost.

func UserError

func UserError(err error) error

UserError annotates err in such a way that IsUserError() can be used further up in the callstack. If err is a wrapped error, the root error will be unwrapped, annotated and rewrapped instead. The root error stack trace is preserved but any middle ones are lost.
