Libraries and frameworks for
Game Development in Rust

Join the Game Development in Rust Discord server

This curated list is from the Game Development in Rust Discord server and prioritizes libraries and frameworks that have examples and are ready or almost ready for production.

For a longer list of libraries and frameworks, see Are We Game Yet?.

The ⭐ emoji means that the framework is excellent for one of the reasons:

• Has many followers and maintainers.
• Might have few followers and maintainers, but is in excellent quality and passed the test of time.
• Uses modern standards (compared to peers).

Rust basics

• Rust book.
• Standard library - Comprehensive guide to the Rust standard library APIs.
• Edition guide - Guide to the Rust editions.
• Cargo book - A book on Rust’s package manager and build system.
• Rustdoc book - Learn how to make awesome documentation for your crate.
• Rustc book - Familiarize yourself with the knobs available in the Rust compiler.
• Compiler error index - In-depth explanations of the errors you may see from the Rust compiler.

Resources to understand ECS (Entity Component System) and DOD (Data-Oriented Design)

ECS/DOD is quite a big deal in Rust. Here are some resources to understand the basics:

• Understanding data-oriented design for entity component systems - Unity at GDC 2019.
• CppCon 2018: Stoyan Nikolov “OOP Is Dead, Long Live Data-oriented Design” - Harsh title (ECS/DOD is not a silver bullet for every problem), but useful regardless.
• RustConf 2018 - Closing Keynote - Using Rust For Game Development by Catherine West - A classic presentation already - Catherine West gives several examples, explain the problems with them, and shows the alternatives.
• "Data-Oriented Design" web book by Richard Fabian.

Productivity tools for game development

• Blender for 3D modeling.
• Krita for 2D image creation.

Game engines

2D + 3D

Recommended if you are going to work with 3D graphics, however, API changes still might happen in future releases.

• bevy Refreshingly simple data-driven game engine.
• fyrox Feature-rich, production-ready, general purpose 2D/3D game engine written in Rust with a scene editor. Formerly known as rg3d.
• hotham lightweight, high performance game engine for standalone VR headsets.

2D

Recommended if you are going to work strictly with 2D graphics.

• emerald
• macroquad
• ggez
• tetra
• oxygengine

Graphics-only

• ⭐ wgpu Cross-platform, safe, pure-rust graphics api (Vulkan, Metal, D3D12, D3D11, OpenGLES, WebGPU).
  • WebGPU specification here.
  • Tutorial here.
• ⭐ ash Low-level bindings to Vulkan.
• ⭐ lyon GPU-based 2D vector rendering. Built on top of wgpu.
• rend3 Easy to use, customizable, efficient 3D renderer library. Built on top of wgpu.
• rafx Multi-backend renderer that prioritizes performance, flexibility, and productivity.
• luminance High level. Built on top of OpenGL.
• miniquad High-level. Focus on portability. Built on top of OpenGL, GLES 3 and WebGl1.
• golem Intermediate-level. Higher level wrapper built on glow.
• vulkano Intermediate-level. Safer wrapper for Vulkan.
• glow Low-level. Safer wrapper for OpenGL and WebGL.
• erupt Low-level bindings to Vulkan.
• ⭐ gl46 Low-level. Wrapper for OpenGL 4.6 (generated by Phosphorus).
• ⭐ gl33 Low-level. Wrapper for OpenGL 3.3 (generated by Phosphorus).
• sierra Low-level control and high-level features. Built on top of erupt.

I believe it is fair to say that if you use libraries built on top of WGPU, you will get wider support on modern platforms (Linux, Windows, MacOS, Android and iOS).

Window creation and OS integration

• ⭐ winit Rusty windowing framework. The de facto standard in the Rust community.
• glfw Rust wrapper for the C GLFW3 library.
• fermium Rust wrapper for the C SDL2 library. Contains more than window creation features.
• sdl2 Rust wrapper for the C SDL2 library. Contains more than window creation features.

Frameworks for ECS

• ⭐ hecs Archetype-based.
• ⭐ yaks Add multi-threading to hecs.
• legion Archetype-based.
• shipyard Sparse-based.
• specs Bitset-based.

See this repository for information on the different types of ECS (archetype, sparse, bitset).

Frameworks for physics and linear math (for 2D and 3D programming)

• ⭐ glam
• ⭐ rapier2d / rapier3d New 2D/3D physics framework from the creator of nphysics2D/nphysics3D. 2D demo and 3D demo.
• nphysics2d / nphysics3d 2D/3D physics.
• cgmath
• nalgebra
• ultraviolet
• vek

Graphical user interface (GUI)

• yakui Combines a layout model inspired by Flutter with the ease-of-use of an immediate mode UI library like Dear Imgui or egui.
• ⭐ egui Pure Rust cross-platform library. Many renderers already have an integration with Egui.
• ⭐ iced Pure Rust cross-platform library.
• imgui Bindings in Rust for the Dear ImGui C++ library.

Font (parser and/or rasterizer)

• fontdue
• swash
• rustybuzz Complete harfbuzz shaping algorithm port to Rust.
• ttf-parser High-level, safe, zero-allocation TrueType font parser.

Space partitioning

• rstar N-dimensional r*-tree implementation
• bvh Bounding Volume Hierarchy, built on top of nalgebra.
• kdtree K-dimensional tree in Rust for fast geospatial indexing and nearest neighbors lookup.
• ncollide 2D Bounding Volume Tree implementation (2d documentation).
• ncollide 3D Bounding Volume Tree implementation (3d documentation).
• spade Implements r*-tree and delaunay triangulation.
• flat_spatial Simple flat structures such as a grid/hashmap of cells.
• acacia Generic over the dimension of the partitioned space and thus supports binary trees, quadtrees, octrees, etc.

Network

• ⭐ tokio Asynchronous TCP and UDP sockets.
• ⭐ quinn QUIC transport protocol implementation. Built on top of tokio.

Audio

• ⭐ oddio Built on top of cpal.
• ⭐ kira Built on top of cpal.
