It would be good to increase the test coverage.

In my opinion we should also add a test example. It may help not only the users but also other reviewers to understand how it is supposed to be used.

It would be good to add benchmarks, but this would be better added as a separate PR. I do not think it is a must-have given that logrus is not used in performance-critical applications.
