Theo is a new vector graphics drawing framework for Rust that aims to provide an easy-to-use API for drawing vector graphics. Developed by John Nunley, Theo is an implementation of piet, a common vector graphics API, that can be used with any windowing system that implements the raw-window-handle traits. One of the main advantages of Theo is its use of GPU acceleration, which allows for improved performance on systems with lower CPU power. Additionally, Theo has minimal dependencies, making it lightweight and easy to integrate into existing systems. Compared to similar solutions like piet-common, Theo offers a more ergonomic and cache-friendly rasterization-based strategy for rendering graphics. The Linebender team is also working on a similar system named Vello, but Theo differentiates itself by its unique approach and simplicity. Developers building GUI systems in Rust should consider giving Theo a try. Check out the examples in the repository for a demonstration of how to use it.
