Async MAVLink
in Rust.

Stack

Arm and take off

Works identically against ArduPilot, PX4, and CrabPilot — the backend handles the differences.

use crablink::Vehicle;

#[tokio::main]
async fn main() -> anyhow::Result<()> {
    // Connect over UDP (ArduPilot SITL default port)
    let mut vehicle = Vehicle::connect(
        "udp:0.0.0.0:14550"
    ).await?;

    // Wait for heartbeat and capabilities
    vehicle.wait_ready().await?;

    // Arm and take off to 10 m
    vehicle.arm(true).await?;
    vehicle.takeoff(10.0).await?;

    // Stream telemetry
    let mut telem = vehicle.telemetry();
    while let Ok(t) = telem.recv().await {
        println!("alt: {:.1} m", t.altitude_rel_m);
    }
    Ok(())
}
