Initialization

Minimal Starting Point

use sdl2::event::Event;

fn main() {
    // initialize SDL contexts and windows
    let sdl_context = sdl2::init().unwrap();
    let video_subsystem = sdl_context.video().unwrap();
    let window = video_subsystem.window("Test", 1280, 720)
        .position_centered()   // centers the window on the screen
        .resizable()           // makes the window resizable
        .build()
        .unwrap();
    let mut canvas = window.into_canvas().build().unwrap();
    let mut event_pump = sdl_context.event_pump().unwrap();

    // present canvas
    canvas.clear();
    canvas.present();

    // render loop
    'running: loop {
        canvas.clear();
        
        // handle events
        for event in event_pump.poll_iter() {
            match event {
                Event::Quit { .. } => {
                    break 'running
                },
                _ => {}
            }
        }
        
        canvas.present();
    }
}
