Matter protocol implementation in Rust

Simple example (preview)

let device_information = DeviceInformation {
    ip,
    mac,
    device_name: "Matter Bulb".to_string(),
    device_type: DeviceType::Light,
    vendor_id: 0xFFF1,
    product_id: 0x8000,
};

let mut device = Device::new(device_information);
device.insert(1, OnOff, cluster::on_off::OnOffCluster::new());
let receiver = matter::start(interface, device);
loop {
    let event = receiver.recv();
    match event {
        OnOff::On => led_pin.enable(),
        OnOff::Off => led_pin.disable()
        _ => log_info!("We're ignoring the rest for now")
    }
}
