mmal-sys VS rutter-pi

Now that we know how to compile and run Rust and Flutter in conjunction on the rpi we want to be able to control the camera from our app. There might be libraries for controlling the camera written in Dart but since we want to use Rust together with Dart, we're going to do it from Rust. I've chosen a library called rascam. It's a small library built on top of mmal-sys. We can add rascam to our Rust project by adding this to the Cargo.toml file:

At Charlie foxtrot we aim to stay relevant and keep up with new and exciting tech. So how do we do that? We experiment! This time we wanted to capitalize on our in-house competence in Flutter and Rust. Our Flutter expert, Jonathan, had read about Darts foreign function interface (ffi) capabilities and wanted to try it in conjunction with Rust. He asked me if I thought if we could build something that would run on a Raspberry pi (rpi). Without having a clue, I said “YES!” and got to work. The resulting code can be found here.
