    /// ## Properties
    ///
    ///
    /// #### `track-type`
    ///  Readable | Writeable | Construct
    /// <details><summary><h4>Asset</h4></summary>
    ///
    ///
    /// #### `extractable-type`
    ///  The [`Extractable`][crate::Extractable] object type that can be extracted from the asset.
    ///
    /// Readable | Writeable | Construct Only
    ///
    ///
    /// #### `id`
    ///  The ID of the asset. This should be unique amongst all assets with
    /// the same [`extractable-type`][struct@crate::Asset#extractable-type]. Depending on the associated
    /// [`Extractable`][crate::Extractable] implementation, this id may convey some information
    /// about the [`glib::Object`][crate::glib::Object] that should be extracted. Note that, as such, the
    /// ID will have an expected format, and you can not choose this value
    /// arbitrarily. By default, this will be set to the type name of the
    /// [`extractable-type`][struct@crate::Asset#extractable-type], but you should check the documentation
    /// of the extractable type to see whether they differ from the
    /// default behaviour.
    ///
    /// Readable | Writeable | Construct Only
    ///
    ///
    /// #### `proxy`
    ///  The default proxy for this asset, or [`None`] if it has no proxy. A
    /// proxy will act as a substitute for the original asset when the
    /// original is requested (see [`Asset::request()`][crate::Asset::request()]).
    ///
    /// Setting this property will not usually remove the existing proxy, but
    /// will replace it as the default (see [`AssetExt::set_proxy()`][crate::prelude::AssetExt::set_proxy()]).
    ///
    /// Readable | Writeable
    ///
    ///
    /// #### `proxy-target`
    ///  The asset that this asset is a proxy for, or [`None`] if it is not a
    /// proxy for another asset.
    ///
    /// Note that even if this asset is acting as a proxy for another asset,
    /// but this asset is not the default [`proxy`][struct@crate::Asset#proxy], then `proxy`-target
    /// will *still* point to this other asset. So you should check the
    /// [`proxy`][struct@crate::Asset#proxy] property of `target`-proxy before assuming it is the
    /// current default proxy for the target.
    ///
    /// Note that the [`notify`][struct@crate::glib::Object#notify] for this property is emitted after
    /// the [`proxy`][struct@crate::Asset#proxy] [`notify`][struct@crate::glib::Object#notify] for the corresponding (if any)
    /// asset it is now the proxy of/no longer the proxy of.
