Best abstraction over epoll/kqueue ? As compared to what ?
From all the things that rust does right, MIO event loop seems lacking as compared to boost::asio for example.
It strikes a good balance of portability and features, and where MIO leaves off, tokio picks up.
When comparing to other libraries in other languages, MIO probably looks like it's devoid of features, but that's because it's trying to be an abstraction layer only, and tokio is probably where most people should turn for higher level semantics...
