Glutin is an OpenGL context creation library and doesn't directly provide OpenGL bindings for you.

gl = "*"
libc = "*"
extern crate gl;
extern crate glutin;
extern crate libc;

use glutin::GlContext;

fn main() {
    let mut events_loop = glutin::EventsLoop::new();
    let window = glutin::WindowBuilder::new()
        .with_title("Hello, world!")
        .with_dimensions(1024, 768);
    let context = glutin::ContextBuilder::new()
    let gl_window = glutin::GlWindow::new(window, context, &events_loop).unwrap();

    unsafe {

    unsafe {
        gl::load_with(|symbol| gl_window.get_proc_address(symbol) as *const _);
        gl::ClearColor(0.0, 1.0, 0.0, 1.0);

    let mut running = true;
    while running {
        events_loop.poll_events(|event| {
            match event {
                glutin::Event::WindowEvent{ event, .. } => match event {
                    glutin::WindowEvent::Closed => running = false,
                    glutin::WindowEvent::Resized(w, h) => gl_window.resize(w, h),
                    _ => ()
                _ => ()

        unsafe {


Note that glutin aims at being a low-level brick in your rendering infrastructure. You are encouraged to write another layer of abstraction between glutin and your application.

Platform-specific notes


To compile the examples for android, you have to use the cargo apk utility.

See the android-rs-glue repository for instructions.

Emscripten with asmjs

In order to use glutin with emscripten, start by compiling your code with --target=asmjs-unknown-emscripten.

Then create an HTML document that contains this:

<canvas id="canvas"></canvas>
<script type="text/javascript">
var Module = {
    canvas: document.getElementById('canvas')
<script type="text/javascript" src="target/asmjs-unknown-emscripten/debug/..." async></script>

Note: adjust the src element of the script to point to the .js file that was produced by the compilation.

The Module object is the link between emscripten and the HTML page. See also this documentation.


  • The plan is that glutin tries to dynamically link-to and use wayland if possible. If it doesn't work, it will try xlib instead. If it doesn't work, it will try libcaca. This is work-in-progress.
