I think you meant the code: if err != nil { return fmt.Errorf("What I was trying to do: %w") } That's the correct and standard way to do error wrapping in Go since Go 1.13[1]. There is also Dave Cheney's pkg/errors[2] which does define "errors.Wrap()", but that has been superseded by the native functionality in Go.
