// Generated by tools/gen_cart_haxe.js - do not edit.

// Usage:
//
// ```haxe
// class Main {
//   static function main() {
//     Null0.onUpdate = () -> {
//       Null0.clear(Null0.BLUE);
//       Null0.drawCircle(100, 100, 50, Null0.RED);
//     };
//   }
// }
// ```
//
// Notes:
//   - haxe try/catch is not supported (the wasm engine carts run in has no
//     exception handling); an uncaught throw aborts the cart.
//   - functions returning structs (Color/Vector/...) return host-owned
//     objects - use them within the current callback, don't stash them.
