func WithStack

func WithStack(err error) error

WithStack returns an error that wraps err and adds the call stack of the call to WithStack to Error(). If err is nil or already has a stack attached, returns err.

Example

err := WithStack(errors.New("foo"))

fmt.Println(strings.Join(strings.Split(err.Error(), "\n")[:3], "\n"))

Output:


foo
