This template should get you started using OpenGL in Rust quickly. It is a minimal template, which just depends on sdl2 for window management and initialization and on gl_generator for providing bindings to the OpenGL API.
To use the template it is recommended to use cargo-generate, which is only needed to setup your project and can be deleted afterwards. Using the template works by executing the following commands:
cargo install cargo-generate
cargo generate --name my-awesome-project --git https://github.com/hrittich/gl-template
To run your program execute the following commands:
cd my-awesome-project
cargo run
Now, you can move on to learning OpenGL. Have fun!
