Getting acquainted with Rust's mio

Out of curiosity, Rust was first built on libuv, then libuv was removed, now mio looks like an API very similar to libuv, but not using libuv. What were the decisions behind this and why is it better than not using an existing lib that should be easy to plug into Rust via FFI since it is small and in C?

Great post. I didn't check mio before but after reading the post I can probably jump start.

I&#x27;m sure event loops have their uses in all languages, but I&#x27;m not sure why the author rubbishes Python and JS, citing callback hell, and then writes an example that uses callbacks.<p>Anyway, the article&#x27;s introduced me to consensus algorithms, so thanks for that.

You lost me there. What&#x27;s this about?
