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.
rust
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.dbustest 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.
rust
let c = Connection::get_private(BusType::Session).unwrap();
c.register_name("com.example.dbustest", NameFlag::ReplaceExisting as u32).unwrap();
let f = Factory::new_fn();
let tree = f.tree().add(f.object_path("/hello").introspectable().add(
f.interface("com.example.dbustest").add_m(
f.method("Hello", |m,_,_| {
let s = format!("Hello {}!", m.sender().unwrap());
Ok(vec!(m.method_return().append(s)))
}).out_arg(("reply", "s"))
)
));
tree.set_registered(&c, true).unwrap();
for _ in tree.run(&c, c.iter(1000)) {}
You can try a similar example by running:
cargo run --example server
This example gets the current version of the Policykit backend.
rust
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
