//! # DBus interface proxy for: `org.asuslinux.Daemon`
//!
//! This code was generated by `zbus-xmlgen` `1.0.0` from DBus introspection
//! data. Source: `Interface '/org/asuslinux/Aura' from service
//! 'org.asuslinux.Daemon' on system bus`.
//!
//! You may prefer to adapt it, instead of using it verbatim.
//!
//! More information can be found in the
//! [Writing a client proxy](https://zeenix.pages.freedesktop.org/zbus/client.html)
//! section of the zbus documentation.
//!
//! This DBus object implements
//! [standard DBus interfaces](https://dbus.freedesktop.org/doc/dbus-specification.html),
//! (`org.freedesktop.DBus.*`) for which the following zbus proxies can be used:
//!
//! * [`zbus::fdo::PeerProxy`]
//! * [`zbus::fdo::IntrospectableProxy`]
//! * [`zbus::fdo::PropertiesProxy`]
//!
//! …consequently `zbus-xmlgen` did not generate code for the above interfaces.
