Embedded programming in Rust

You might want to look at this topic. Also there was a rust skeleton project for the adroino due on github, sadly I do not remember it's name.

And I do recommend using a "proven" environment/hardware witch is not too complicate, documented and also does support rust (e.g. some working skeleton/example project exists).

The mentioned skeleton is dueboot.
Through it's last commit was half a year ago, so it might not be working out of the box.
