Howdy there developer 👋
It's already August! Can you believe it?
In this issue, look forward to reading about Quilkin, our brand-new opensource game server proxy; Tower, a crate designed to help you build robust networking clients, initial raytracing support in rust-gpu, Rust community events, and more!
New to the newsletter? Welcome! I'm Celia, a Producer here at Embark. Every now and then I'll send you a summary of what Embark's been up to in open source and the greater developer ecosystem.
Let me know what you think! You can send feedback about the newsletter or questions to opensource@embark-studios.com.

Introducing Quilkin: an open-source game server proxy by Embark Studios & Google Cloud
Quilkin is a non-transparent UDP proxy specifically designed for use with large scale multiplayer dedicated game servers deployments, to ensure security, access control, telemetry data, metrics and more. It is designed to be used behind game clients as well as in front of dedicated game servers.
We think leveling the playing field for everyone in the games industry is an important and worthy endeavor. That’s why we collaborated with Google Cloud and initiated this project together.

"We’re aiming for Quilkin to be able to run in a variety of different setups — from running as a sidecar to the game-server exposing useful metrics, running in a large pool as a DDOS protection layer, absorb large amounts of invalid traffic, all the way to running on the edge as shown above and provide flexibility to the game client, so it can pick the Quilkin edge that provides the best latency for player traffic."
- Luna Duclos, Tech Lead | Backend Delivery

Quilkin is a UDP proxy, tailor-made for high performance real-time multiplayer games. Its aim is twofold:
-
Pull common functionality, such as security, access control, telemetry and metrics out of monolithic dedicated game servers and clients.
-
Provide this common functionality in a composable and configurable way, such that it can be reused across a wide set of multiplayer games.

New Article: Inventing the Service Trait with Tower
Tower aims to make it as easy as possible to build robust networking clients and servers with Rust. How does it accomplish this? Using a simple core abstraction, the Service trait, which represents an asynchronous function taking a request and returning either a response or an error.
If you're curious to read a thorough breakdown of how a simple trait came to power an impressive networking crate, one of our software engineers, David Pederson, wrote an article on Inventing the Service Trait.
For even more Tower goodness, David also wrote a write-up highlighting the recent announcement of the tower-http crate, a collection of HTTP specific middleware and utilities built with Tower's Service trait.

🐉 rust-gpu: Initial support for raytracing and 159 new commits later...
Since the announcement of rust-gpu v0.3 in our last newsletter, 160 commits have been made to the project. Wow! That includes fantastic things like:
- Initial support for raytracing.
- Overhauled the way SPIR-V capabilities are specified, going from a huge hack to a nice system.
- Added procedural macro to define the hundreds of potential configurations of image types
... and 157 other small (but equally important!) changes and improvements made by contributors like you. We'd like to say a special thanks to some of our most active external contributors on rust-gpu, including:

Projects from the Rustiverse 🪐: Rocket
This month, we want to highlight the project Rocket, an async web framework for Rust with a focus on usability, security, extensibility, and speed. With robust documentation and a beginner-friendly Getting Started guide, Rocket is a great crate for those looking to try out web programming in Rust. The project is also always actively looking for contributors, with 57 issues open as of today!
If you're more inclined to learn via video than read documentation, Rainer Stropek of Rust Linz also has a fantastic introduction to Web APIs and Rocket you can check out to get yourself started.

Contributors of the Month
Community is all about people, and we’re grateful to have you along with us on our journey. That's why we want to take the time to highlight the contributions, small and large, that developers like you add to our projects.
Last month, we highlighted contributions to rust-gpu, one of our fastest growing projects. This month, we wanted to highlight the contributions of 2 developers that added to our smaller crates: cfg-expr and tame-oauth.
Crate: cfg-expr
Enabled cfg-expr to build with Rust 1.52.
Solomon Boulos (boulos)
Crate: tame-oauth
Added EndUserCredentials and implement get_default_google_credentials
