Rustbus

Rustbus is a dbus library that allows for RPC on services on the bus or to implement your own service that listens on the bus. There are some examples in the src/bin directory but the gist is:

use rustbus::{get_session_bus_path, standard_messages, Conn, Container, params::DictMap, MessageBuilder};

fn main() -> Result<(), rustbus::client_conn::Error> {
// Connect to the session bus
let session_path = get_session_bus_path()?;
let con = Conn::connect_to_bus(session_path, true)?;

// Wrap the con in an RpcConnection which provides many convenient functions
let mut rpc_con = rustbus::client_conn::RpcConn::new(con);

// send the obligatory hello message
rpc_con.send_message(&mut standard_messages::hello(), None)?;

// Request a bus name if you want to
rpc_con.send_message(&mut standard_messages::request_name(
"io.killing.spark".into(),
0,
), None)?;

// send a signal to all bus members
let mut sig = MessageBuilder::new()
.signal(
"io.killing.spark".into(),
"TestSignal".into(),
"/io/killing/spark".into(),
)
.with_params(vec![
Container::Struct(vec![162254319i32.into(), "AABB".to_owned().into()]).into(),
])
.build();
rpc_con.send_message(&mut sig, None)?;
Ok(())
