Rust＆GTK 3.如何创建包含glib :: Value类型的元素的数组，可以将其转换为＆[＆ToValue]类型？

我正在使用Rust和GTK 3绑定创建GUI应用程序（称为Gtk-rs或rust-gnome） . 我想使用方法insert_with_values将一些数据插入 gtk::ListStore （ GtkListStore ）

Working sample, but only one column: 如果我有一列，我可以插入数据：

let type_of_a_column = &[gtk::Type::U32];
let data_for_column_1 = (2 as u32).to_value();
let model_list_of_data = ListStore::new(type_of_a_column);
model_list_of_data.insert_with_values(None, &[0 as u32], &[&data_for_column_1]);

但是，如果我有更多列，我不知道如何移交更多数据 . 我知道在内部它应该调用gtk_list_store_insert_with_valuesv()所以我可能需要一个数组或切片，但如果我做了类似的事情：

Wanted to pass two elements in array, not working

let type_of_a_column = &[gtk::Type::U32, gtk::Type::I64];
let data_for_column_1 = (2 as u32).to_value();
let data_for_column_2 = (4 as i64).to_value();
let array_of_data = [&data_for_column_1, &data_for_column_2];
let model_list_of_data = ListStore::new(type_of_a_column);
model_list_of_data.insert_with_values(None, &[1 as u32], &[&array_of_data]);

它在编译期间给了我：

错误：特征界限[＆glib :: Value; 2]：不满足glib :: IsA <glib :: Object> [E0277]

我不知道如何克服它 .

    model_list_of_data.insert_with_values(Some(0), &[0 as u32, 1 as u32], &[&array_of_data]);

    view_list.set_model(Some(&model_list_of_data));
    box_container.pack_start(&view_list, false, false, 0);
    window.add(&box_container);
