A day for smaller works. :)
I've updated the horribly outdated Periodic Table of Rust Types. The resulting table seems a lot clearer than the previous. I've also received a series of suggestions and reports of mistakes (oops) from /r/rust.
I've also pushed a MaybeUTF8 library.
This was originally a part of rust-zip library,
but this is slightly undermaintained than zip-rs,
and I basically kept it just compilable in the recent nightly.
In the long term I plan to merge some design of rust-zip into zip-rs,
and as a preparation I've separated this into a separate crate.
MaybeUTF8 was what newer nightlies liked to break, anyway.
