I am trying to use the dbus crate to get the address, netmask, DNS and gateway.

if let Some(ip4_config_path) = props.get("Ip4Config").and_then(|v| v.0.as_str()) {
if ip4_config_path != "/" {
    let ip4_proxy = connection.with_proxy(".freedesktop.NetworkManager",ip4_config_path,Duration::from_millis(5000),);
    
    let (config,): (PropMap,) = ip4_proxy.method_call(".freedesktop.DBus.Properties","GetAll",(".freedesktop.NetworkManager.IP4Config",),)
                                .map_err(|e| format!("Failed to get IP config: {}", e))?;
    
    eprintln!("Config {:?}", config);
    
    let address_data = config.get("AddressData");
    eprintln!("address_data {:?}", address_data);

Here when I print the address_data it shows as

"AddressData": Variant(InternalArray { data: [{"prefix": Variant(24), "address": Variant("192.168.100.20")}], inner_sig: Signature("a{sv}\0") })

So, now I am stuck at how to read the IP-address from this?
