2D, 3D and more? These are Rust Game Engines.

Why Choose Rust?

Rust, originally developed by Mozilla and now maintained by an active open-source community, is a low-level programming language that offers exceptional control over hardware and performance. Its standout feature is memory safety, achieved through an ownership and borrowing system that eliminates the need for a garbage collector. This makes Rust an excellent choice for game development, ensuring high performance and stability without memory leaks.

Rust in Game Development

The Rust game engines' popularity in game development is due to its speed, safety, and efficient memory management. These attributes are vital for creating high-performance games with robust code, minimizing bugs and crashes. Rust’s low-level control enables optimized code, essential for smooth gameplay and impressive graphics.
