Crate romio requires nightly, is it the issue for missing docs?

Fixes withoutboats/romio#44

Attempting to build it by hand with the latest nightly rustc yields the following log:

This tells me it's not a problem of needing a new rustc, but a new cargo. Updating cargo on docs.rs requires updating the site itself, since it uses cargo as a library. I'll work on this once the Rustdoc Team gets permission on the recently-moved repo and our CI gets updated.

@onur Would you please trigger the build for romio to see whether the fix worked or not?
