#[dbus_proxy(
    interface = "org.freedesktop.UPower.Device",
    default_service = "org.freedesktop.UPower"
)]
trait Device {
    /// Type property
    #[dbus_proxy(property)]
    fn r#type(&self) -> zbus::Result<u32>;
}

Fails:

Is this with 1.x or latest 2.0 beta?

Any easy work around is to make use of name attribute to avoid keywords:

    #[dbus_proxy(property, name = "Type")]
    fn type_(&self) -> zbus::Result<u32>;

@zeenix Thanks for the workaround! This affects current master branch as well as latest beta.
