Use Rust to interact with Microsoft Flight Simulator

As seen in the FlyByWire A32NX and A380X!

• Write custom aircraft logic in Rust
  • Systems
  • Gauges
  • Instrument panels (NanoVG)
  • Replace aircraft code
    • RPL
    • C++
    • JavaScript
    • TypeScript
    • WASM
• Interact with the Microsoft SDK
• Create external applications that interact with MSFS using SimConnect

Example

Drawing a red rectangle on a glass instrument panel inside an aircraft cockpit:

// gauge_logic.rs
use msfs::{nvg, MSFSEvent};

#[msfs::gauge(name=Demo)]
async fn demo(mut gauge: msfs::Gauge) -> Result<(), Box<dyn std::error::Error>> {
    // Use NanoVG to draw
    let nvg = gauge.create_nanovg().unwrap();

    let black = nvg::Style::default().fill(nvg::Color::from_rgb(0, 0, 0));
    let red = nvg::Style::default().fill(nvg::Color::from_rgb(255, 0, 0));

    // Reacting to MSFS events
    while let Some(event) = gauge.next_event().await {
        match event {
            MSFSEvent::PreDraw(d) => {
                nvg.draw_frame(d.width(), d.height(), |f| {
                    // Red rectangle
                    f.draw_path(&red, |p| {
                        p.rect(20.0, 20.0, 40.0, 40.0);
                        println!("Hello rusty world!");

                        Ok(())
                    })?;

                    Ok(())
                });
            }
            _ => {}
        }
    }
    Ok(())
}
