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)
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 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
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
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
