Issues with the tutorial

[ryzendew]

so here https://docs.slint.dev/latest/docs/slint/tutorial/creating_the_tiles/

it asked you to do

fn main() {
    use slint::Model;

    let main_window = MainWindow::new().unwrap();

    // Fetch the tiles from the model
    let mut tiles: Vec<TileData> = main_window.get_memory_tiles().iter().collect();
    // Duplicate them to ensure that we have pairs
    tiles.extend(tiles.clone());

    // Randomly mix the tiles
    use rand::seq::SliceRandom;
    let mut rng = rand::thread_rng();
    tiles.shuffle(&mut rng);

    // Assign the shuffled Vec to the model property
    let tiles_model = std::rc::Rc::new(slint::VecModel::from(tiles));
    main_window.set_memory_tiles(tiles_model.clone().into());

    main_window.run().unwrap();
}

This leads to an Error

   Compiling slint-rust-template v0.1.0 (/home/mattscreative/Documents/slint-rust-template-main)

Some errors have detailed explanations: E0412, E0433.
For more information about an error, try `rustc --explain E0412`.
error: could not compile `slint-rust-template` (bin "slint-rust-template") due to 2 previous errors

it also breaks things in app-window.slint

Wondering if i messed something up?

[ogoffart]

The struct TileData should be defined on the .slint file from previous steps.
Same for the Main window.

Do you still have the slint::include_modules!(); line to include the generated code?
