Example code:

struct App {
    throbber_state: throbber_widgets_tui::ThrobberState,
}
impl App {
    fn on_tick(&mut self) {
        self.throbber_state.calc_next();
    }
}
// :
// :
fn ui(f: &mut ratatui::Frame, app: &mut App) {
    let chunks = ratatui::layout::Layout::default()
        .direction(ratatui::layout::Direction::Horizontal)
        .margin(1)
        .constraints(
            [
                ratatui::layout::Constraint::Percentage(50),
                ratatui::layout::Constraint::Percentage(50),
            ]
            .as_ref(),
        )
        .split(f.area());

    // Simple random step
    let simple = throbber_widgets_tui::Throbber::default();
    f.render_widget(simple, chunks[0]);

    // Set full with state
    let full = throbber_widgets_tui::Throbber::default()
        .label("Running...")
        .style(ratatui::style::Style::default().fg(ratatui::style::Color::Cyan))
        .throbber_style(ratatui::style::Style::default().fg(ratatui::style::Color::Red).add_modifier(ratatui::style::Modifier::BOLD))
        .throbber_set(throbber_widgets_tui::CLOCK)
        .use_type(throbber_widgets_tui::WhichUse::Spin);
    f.render_stateful_widget(full, chunks[1], &mut app.throbber_state);
}
