Emscripten Rust/C Template

This is a template for an emscripten project with a "Rust backend".

Setting up

(Note that this has only been tested in a Linux environment.)

1. Clone https://github.com/emscripten-core/emsdk to ${HOME}/git/emsdk.
2. Set up emsdk with ${HOME}/git/emsdk/emsdk install latest and ${HOME}/git/emsdk/emsdk activate latest.
3. Set up rustup.
4. Get the wasm32-unknown-emscripten target with rustup target add wasm32-unknown-emscripten.

Build

Just run make in the root of this project.

Other Notes

The current set up of the update/draw loop uses emscripten_set_main_loop_arg(...) with parameters that should call the browser's requestAnimationFrame that should call update and draw once per each frame at the fps that the browser decides, which should match the fps of your display.

If you want to use graphics, I suggest using/building raylib, but that will require building it separately with emsdk and linking to it in the Makefile.
