Dealing with D-Bus in your code can be a bit tedious. These macros makes the task simpler. They are inspired by Vala's awesome D-Bus support.
This example serves a bunch of methods on an object
extern crate dbus;
#[macro_use]
extern crate dbus_macros;
use dbus::{Connection, BusType};
use std::rc::Rc;
dbus_class!("com.dbus.test", class Hello (variable: i32) {
fn hello(&this) -> String {
"Hello!"
}
fn hello_with_name(&this, name: &str) -> String {
format!("Hello, {}!", name)
}
fn get_variable(&this) -> i32 {
this.variable
}
});
fn main() {
let variable = 24;
let session_connection = Connection::get_private(BusType::Session).unwrap();
let hello = Hello::new(variable);
hello.run("com.dbus.test", &session_connection, "/Hello");
}
You can try a similar example (which has more methods) by running:
cargo run --example server
This example opens a connection to the server example above and calls its methods.
extern crate dbus;
#[macro_use]
extern crate dbus_macros;
use dbus::{Connection, BusType};
use std::rc::Rc;
dbus_interface!("com.dbus.test", interface Hello {
fn hello() -> String;
fn hello_with_name(name: &str) -> String;
fn get_variable() -> i32;
});
fn main() {
let session_connection = std::rc::Rc::new(dbus::Connection::get_private(dbus::BusType::Session).unwrap());
let hello = Hello::new("com.dbus.test", "/Hello", session_connection);
match hello.hello() {
Ok(string) => println!("{}", string),
Err(error) => println!("Error calling DBus service: {}", error),
}
println!("{}", hello.hello_with_name("World").unwrap());
println!("{}", hello.get_variable().unwrap());
}
You can try a similar example (that tries more method calls on the server example) by running:
cargo run --example client
dbus 0.5 or higher, but it's handled for you by the cargo system.
