It doesn't really have much RAM, I don't know how useful Rust would be for anything but prototyping, I don't think there's been much focus on size optimizations.

You can compile Rust without the stdlib, how much memory you use is then up to you. Code size is not an issue, 4MB of flash are common now.

We actually added a "optimize for size" flag pretty recently.

Wow. How do you track that someone mentioned Rust. You are a machine Sir. :)

Mentioning Rust on HN inevitably summons Steve Klabnik. Its just the way it works.

I read a lot of HN. :)
