    /// The sorter returned by [`ColumnView::sorter()`][crate::ColumnView::sorter()] is
    /// a [`ColumnViewSorter`][crate::ColumnViewSorter].
    ///
    /// In column views, sorting can be configured by associating

    /// on column headers. The API of [`ColumnViewSorter`][crate::ColumnViewSorter] is designed
    /// to allow saving and restoring this configuration.
    ///
    /// If you are only interested in the primary sort column (i.e. the
    /// column where a sort indicator is shown in the header), then
    /// you can just look at [`primary-sort-column`][struct@crate::ColumnViewSorter#primary-sort-column]
    /// and [`primary-sort-order`][struct@crate::ColumnViewSorter#primary-sort-order].
    ///
    /// If you want to store the full sort configuration, including
    /// secondary sort columns that are used for tie breaking, then
    /// you can use [`nth_sort_column()`][Self::nth_sort_column()].
    /// To get notified about changes, use [`changed`][struct@crate::Sorter#changed].
    ///
    /// To restore a saved sort configuration on a [`ColumnView`][crate::ColumnView],
