I can only guess, but I do think that it does depend on at least one of the following:
- Rust is not officially taught on my university.
- Rust would make the graphics course unnecessary complex due to life time restrictions
- There is no LLVM code gen available for that device, only a propretiary compiler for that C-like language
- Rust is not available in official Ubuntu 14.04 repositories
- Rust is much newer than the current curricula (my curriculum is from 2011)
- No sane student wants to learn a new language AND a new topic at the same time
- Most other students at my university appear to be very monoglottish… Evangelizing the language used at their sidejob while using languages taught as less much as necessary and as less as possible…
