Embark Rust Ecosystem

Embark logo

High-level tracking and discussions about improving Rust and the Rust ecosystem for our game development use cases at Embark.

Check out the Issues for active topics.


When we started Embark, we chose Rust as our primary language for the long term future we are building. We love the safety and robustness of the language, the ability to write high performance, safe, and (mostly) bug free code and then fearlessly refactor and change it without common lifetime/ownership, memory safety or race condition problems.

That, combined with the openness and collaborative nature of the quickly growing ecosystem of and around Rust with and the tens of thousands of open source crates with a best-in-class package system, cargo, truly makes Rust a language for the next 40 years.

We believe that by openly sharing our work, issues, and ideas with the community, we'll create more opportunities for collaboration and discussion to bring us toward a great future for Rust and for the games industry in general.

-- Johan Andersson (@repi), CTO, Embark

Areas of Interest

Areas that we are interested in or working on, and want to help see improved in Rust:

  • ☸ Distributed systems - async, tokio, tonic

  • πŸ•ΉοΈ Game engine systems - multiplayer, rendering, physics, audio, server, assets, workflows

  • πŸ“¦ Developer experience - fast iteration with large projects/monorepos, distributed builds, debugging, profiling, IDE

  • πŸ›Έ WebAssembly and WASI - sandboxed safe Rust code on client, edge & cloud

  • πŸ€– Machine learning - efficient inference, library bindings, training environments

  • πŸš€ High performance runtime - CPU job scheduling, code generation, optimizing crates

  • πŸ“ΊπŸ“± Console & mobile platform support - PlayStation, Xbox, Android. #18

  • 🏎 Rust on GPU - future compute & ML programming models beyond shaders,

We track and discuss these from our perspective in the Issues for visibility and to get feedback, feel free to join in if you have ideas!
