A DBus binding for rust.

Current state: WIP, but these things should be up and working:

• Connect to system or session bus
• Method calls send/receive
• Signals send/receive
• Properties, on both client and server sides (set/get/getall methods, but no signals)
• Server side introspection
• Server side method dispatch (boxed closures) and property get/set dispatch (trait objects)

Examples

Client

This example opens a connection to the session bus and asks for a list of all names currently present.

let c = Connection::get_private(BusType::Session).unwrap();
let m = Message::new_method_call("org.freedesktop.DBus", "/", "org.freedesktop.DBus", "ListNames").unwrap();
let mut r = c.send_with_reply_and_block(m, 2000).unwrap();
let reply = r.get_items();
println!("{}", reply);

You can try a similar example by running:

cargo run --example client

Server

This example grabs the com.example.test bus name, registers the /hello path and adds a method which returns a string. It then listens for incoming D-Bus events and handles them accordingly.

let c = Connection::get_private(BusType::Session).unwrap();
c.register_name("com.example.test", NameFlag::ReplaceExisting as u32).unwrap();

let mut o = ObjectPath::new(&c, "/hello", true);
o.insert_interface("com.example.test", Interface::new(
    vec!(Method::new("Hello", vec!(),
        vec!(Argument::new("reply", "s")),
        Box::new(|msg| Ok(vec!(MessageItem::Str(format!("Hello {}!", msg.sender().unwrap())))))
    )),
    vec!(), vec!()
));
o.set_registered(true).unwrap();

for n in c.iter(1000) {
    match n {
        ConnectionItem::MethodCall(mut m) => {
            o.handle_message(&mut m);
        },
        _ => {},
    }
}

You can try a similar example by running:

cargo run --example server

Properties

This example gets the current version of the Policykit backend.

let c = Connection::get_private(BusType::System).unwrap();
let p = Props::new(&c, "org.freedesktop.PolicyKit1", "/org/freedesktop/PolicyKit1/Authority",
    "org.freedesktop.PolicyKit1.Authority", 10000);
let v = p.get("BackendVersion").unwrap();

You can try a this example by running:

cargo run --example properties
