Plans for Rust

I plan on using Rust (http://www.rust-lang.org/) for problem 40 - I have already read plenty of documentation and worked out the necessary algorithms on paper. However, after spending about 20 minutes trying to install rust, it overfilled my hard drive, causing my computer to crash and on reboot to be unable to go past the console. So, I will need to try to find the room on my computer (or some other computer) before actually getting a solution running.
