Overview

Package err define error type of uexky

Use uerr.New and uerr.Errorf to create custom errors. Use uerr.Wrap and uerr.Wrapf to wrap extern errors. To transit error in this project, just use errors.Wrap and errors.Wrapf, the wrapped message is function name and parameters. Follow this guideline, we will get clear error stack.
