//! # D-Bus interface proxy for: `org.mpris.MediaPlayer2.Player`
//!
//! This code was generated by `zbus-xmlgen` `4.1.0` from D-Bus introspection data.
//! Source: `Interface '/org/mpris/MediaPlayer2' from service 'org.mpris.MediaPlayer2.playerctld' 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] section of the zbus
//! documentation.
//!
//! This type implements the [D-Bus standard interfaces], (`org.freedesktop.DBus.*`) for which the
//! following zbus API can be used:
//!
//! * [`zbus::fdo::PropertiesProxy`]
//! * [`zbus::fdo::IntrospectableProxy`]
//! * [`zbus::fdo::PeerProxy`]
//!
//! Consequently `zbus-xmlgen` did not generate code for the above interfaces.
