Rust, Wasm and the Crazyflie

For quite a while now, I have been very interested in the Rust programming language and since Jonas joined us we are two rust-enthusiast at Bitcraze. Rust is a relatively recent programming language that aims at being safe, performant and productive. It is a system programming language in the sense that it compiles to machine code with minimal runtime. It prevents a lot of bugs at compile time and it provides great mechanisms for abstraction that makes it sometime feels as high level as languages like Python.
I have been interested in applying my love for Rust at Bitcraze, mostly during fun Fridays. There is two area that I have mainly explored so far: Putting Rust in embedded systems to replace pieces of C, having such a high-level-looking language in embedded is refreshing, and re-writing the Crazyflie lib on PC in rust to make it more performant and more portable. In this blog post I will talk about the later, I keep embedded rust for a future blog post :).
To re-implement the Crazyflie lib, the easiest it to follow the way the communication stack is currently setup, more information can be found on Crtp in a pevious blog post about the Crazyflie radio communication and the communication reliability.
