Rust provides an alternative to C/C++ for programming Arduino Due boards. It offers memory safety without garbage collection, built-in unit testing, and compiles to ARM. Some challenges remain around heap allocations, interrupts, and complex language features. Proper testing is important as even single bit errors can cause software issues in real-world systems like automobiles.

2. Source: https://github.com/tkellogg/dueboot
Getting started on OSX:
• http://arduino.cc/en/Guide/ArduinoDue
• brew install rust
• brew install llvm --all-targets
• edit Rakefile of dueboot repository

4. • As fast as C/C++
• No manual memory management, no GC
• Functional goodies
• Built-in unit testing
• Polymorphism (but no inheritance)
• Compiles to ARM (Android, Raspberry Pi, Due)

6. CPU Power?
Battery Life?
Quality?

8. "We've demonstrated how as little
as a single bit flip can cause the
driver to lose control of the engine
speed in real cars due to software
malfunction that is not reliably
detected by any fail-safe"

9. • Buffer overflow
• Unsafe casting
• Race conditions between tasks

12. Remaining Issues
• Heap allocations
• Interrupts as Tasks
• Non-trivial language features
