Yes, and while that's what 0.x usually means, in the Rust community (and in other communities) it's usually more complicated than that. For mio in particular it's been a crate that a lot of folks have been using and it's been working fine. I'm not saying that that's the message that the version number broadcasts. You're totally right that it broadcasts a message that the crate is immature. I'm saying that the actual situation is not as bad as it sounds. Fair point about the bugs :) I wasn't aware of them, and I've only heard really good things about mio.
