Hi Richard,
Maybe it's just too premature to package rust if the language is that unstable ;)
This is pretty much unavoidable, since Firefox is going to ship pieces written in Rust soon... (I think they are already using some Rust code Nightlies, eventually those will graduate to become part of stable releases [1].)
Stefan.
[1] I am not 100% sure about the timeline. I am only sure that Firefox is going to contain a whole bunch of Rust pretty soon.
Forgive me if I am off-topic here (ignore me if I am), but this thread motivated me to add rust to my list of CSV performances: http://tux.nl/Talks/CSV6/speed5.html That work is based on "The CSV game" by Ewan Higgs: https://bitbucket.org/ewanhiggs/csv-game but with the focus on different ways to parse in perl I wanted to add rust the same way Ewan did in https://bitbucket.org/ewanhiggs/csv-game/src/0dd4ca3abeb52044bad7ba39ac86694... On TumbleWeed, I don't need to add repositories and I can install and build and run the examples $ rpm -q rust cargo rust-1.10.0-1.2.x86_64 cargo-0.13.0-1.1.x86_64 And all goes as planned.
