Crate dbus_message_parser[−][src]
Expand description
A library to encode and decode DBus message.
Example
The following examples show how to create a METHOD_CALL
message and a SIGNAL
message.
use bytes::{Bytes, BytesMut};
use dbus_message_parser::message::Message;
use dbus_message_parser::value::Value;
use std::convert::TryInto;
fn create_method_call() {
// Create a MessageCall
// Arguments:
// 1. destination
// 2. object path
// 3. interface
// 4. method
let mut msg = Message::method_call(
"destination.address".try_into().unwrap(),
"/object/path".try_into().unwrap(),
"interface.name".try_into().unwrap(),
"MethodName".try_into().unwrap(),
);
// Add the first argument to the MessageCall
msg.add_value(Value::String("String Argument".to_string()));
// Add the second argument to the MessageCall
msg.add_value(Value::Uint32(0));
println!("{:?}", msg);
let bytes = msg.encode().unwrap();
println!("{:?}", bytes);
}
fn create_signal() {
// Create a Signal
// Arguments
// 1. object path
// 2. interface
// 3. Signal name
let mut signal = Message::signal(
"/object/path".try_into().unwrap(),
"interface.name".try_into().unwrap(),
"SignalName".try_into().unwrap(),
);
// Add the first argument to the MessageCall
signal.add_value(Value::Uint32(0));
// Add the second argument to the MessageCall
signal.add_value(Value::Double(1.0));
println!("{:?}", signal);
let bytes = signal.encode().unwrap();
println!("{:?}", bytes);
}
fn decode_method_call() {
// A message encoded as bytes
let bytes = Bytes::copy_from_slice(
