Panic in zvariant: thread 'main' panicked at 'index out of bounds: the len is 10 but the index is 10'
Given this example program:
use std::error::Error;
use std::convert::TryInto;
use zbus::{dbus_interface, fdo};
struct Foo;
#[dbus_interface(name = "com.grahamc.Foo1")]
impl Foo {
fn bar(&self, name: &str, arg: &str) -> String {
format!("Hello {} {}!", name, arg)
}
}
fn main() -> Result<(), Box<dyn Error>> {
let connection = zbus::Connection::new_session()?;
fdo::DBusProxy::new(&connection)?.request_name(
"com.grahamc.Foo",
fdo::RequestNameFlags::ReplaceExisting.into(),
)?;
let mut object_server = zbus::ObjectServer::new(&connection);
object_server.at(&"/com/grahamc/Foo".try_into()?, Foo)?;
loop {
println!("hello");
if let Err(err) = object_server.try_handle_next() {
eprintln!("{}", err);
}
}
}When I run call this method incorrectly:
[grahamc@Petunia:~]$ busctl --user call com.grahamc.Foo /com/grahamc/Foo com.grahamc.Foo1 Bar s "hello"
Call failed: Message recipient disconnected from message bus without replyingI get the following panic:
