Usage

Winit is a window creation and management library. It can create windows and lets you handle events (for example: the window being resized, a key being pressed, a mouse movement, etc.) produced by window.

Winit is designed to be a low-level brick in a hierarchy of libraries. Consequently, in order to show something on the window you need to use the platform-specific getters provided by winit, or another library.

```rust use winit::{ event::{Event, WindowEvent}, event_loop::{ControlFlow, EventLoop}, window::WindowBuilder, };

fn main() { let eventloop = EventLoop::new(); let window = WindowBuilder::new().build(&eventloop).unwrap();

event_loop.run(move |event, _, control_flow| {
    match event {
        Event::WindowEvent {
            event: WindowEvent::CloseRequested,
            window_id,
        } if window_id == window.id() => *control_flow = ControlFlow::Exit,
        _ => *control_flow = ControlFlow::Wait,
    }
});

} ```

Winit is only officially supported on the latest stable version of the Rust compiler.

Cargo Features

Winit provides the following features, which can be enabled in your Cargo.toml file: * serde: Enables serialization/deserialization of certain types with Serde.

Platform-specific usage

Emscripten and WebAssembly

Building a binary will yield a .js file. In order to use it in an HTML file, you need to:

• Put a <canvas id="my_id"></canvas> element somewhere. A canvas corresponds to a winit "window".
• Write a Javascript code that creates a global variable named Module. Set Module.canvas to the element of the <canvas> element (in the example you would retrieve it via document.getElementById("my_id")). More information here.
• Make sure that you insert the .js file generated by Rust after the Module variable is created.
