Parse input arguments about dbus-rs HOT 6 CLOSED

Found it! I can get the string by using
if let Some(&MessageItem::Str(ref s)) = msg.get_items().get(0)

But that means the "Input arguments" vec can be left empty and has not effect. Are those for different purpose?

Sorry, I don't understand this question. But maybe I could try to make use of the from/into traits to make conversion to and from MessageItem more ergonomic.

In the Method::new there are parameters which are vectors for input and output parameters. I'm not sure how to use theses. Even leaving the input vec parameters empty like in the server example code I can receive and parse input argument if sent by the client side. Are these vectors only for introspection?

Ok. Thanks!

I've now done that, so instead of

if let Some(&MessageItem::Str(ref s)) = msg.get_items().get(0)

you can now also write:

let s: &str = try!(try!(msg.get_items().get(0).ok_or(())).inner());

or perhaps:

let s: &str = try!(msg.get_items().get(0).ok_or(()).map(|s| s.inner()));
