Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

could not find tokio in webrtc_unreliable
The Cargo.toml on GitHub has the optional dependency specified correctly.

How are rust devs doing?
I use WebRTC for multiplayer, and Rust has a great library (webrtc-unreliable) To be fair, C++ has libdatachannel which I like using too.

What are the differences between UDP and WebSockets, and which type of games benefit from which?
You can, in theory, get UDP-like characteristics out of a different web API - with a WebRTC datachannel configured to be unreliable and unordered. I haven't seen anybody use that API just because it's a pretty big pain to use. The developer of Agar IO called it too hard to use in a HackerNews comment, but nowadays there's simpler libraries than the ones he had in 2016 like webrtc-unreliable and libdatachannel. You still need to run a STUN/TURN server and the integration is easier than it was back then, but still much harder than raw UDP sockets though.

A pure Rust implementation of WebRTC API.
Take a look at webrtc-unreliable. I haven't tried it, but it claims to implement just a simple subset of webrtc to get udp-like functionality.

Is rust suitable for multiplayer games?

Someday, maybe, we will be game. I hope.
"While the ecosystem is still very young, you can find enough libraries and game engines to sink your teeth into doing some slightly experimental gamedev."

Egregoria is a city simulation with high granularity
I think Rust for games has come really far. I will cite https://arewegameyet.rs/ "Almost. We have the blocks, bring your own glue.".
All the blocks are there and the language is really well suited to games.
On top of my head:
The pros:
- The crate ecosystem and the package manager makes it really easy to integrate any useful component such as pathfinding, spatial partitioning, graphics backend, audio system.. Most crates take a lot of effort to be cross-platform so I can develop on linux and not spend too much time debugging windows releases.
- The strong typing and algebraic data types makes expressing the game state very pleasant. I also found I was able to develop a very big game without too many bugs even though I don't write many tests.
- Ahead of time compilation + LLVM guarantees you won't have to optimise for weird things around a virtual machine. Rust gives you more control to optimise hot loops as you can go low-level.
- I find wgpu to be the perfect balance between ergonomics and power compared to Vulkan. OpenGL support through wgpu is also a nice addition for lower end devices.
- The Rust community is very helpful, you can often talk directly to crate maintainers
The cons:
- Compilation times, when compared to JITed languages such as C# can be very painful. It can be alleviated by buying a 3950X but I still often get 10-30s iteration times.
- The static nature of Rust means you often need a dynamism layer above to tweak stuff that can be awkward to manage. I made inline_tweak for this purpose but it's really far from how easy Unity makes it. https://github.com/Uriopass/inline_tweak
- Since Rust feels very ergonomic, you are tempted to write almost all game logic within it, so mod support feels very backwards to implement as you cannot really tweak "everything" like in Unity games. Thankfully "Systems" game like Factorio or Egregoria can be theoretically split into the "simulation" and the "entities" so mod can still have a great impact. Factorio is built in C++ so has the same problematic. Their Lua API surface is quite insane to be able to hook into everything. https://lua-api.factorio.com/latest/
Now, I have to talk about Bevy: https://bevyengine.org/. It did not exist when I started but it is a revolution in the Rust gamedev space. It is a very powerful 100% Rust game engine that makes you write game code in Rust too. It has incredible energy behind it and I feel like if I'd used Bevy from the start I wouldn't have had to develop many core engine systems. Its modular design is also incredibly pleasant as you can just replace any part you don't like with your own.

Struggling to find practical uses for Rust
For practical uses of Rust? Whatever you want to program. People use Rust for game development, GUIs, web dev, and more. Anything where abstraction, speed, concurrency, memory safety, etc. are important, Rust will probably be a good fit.

Really frustrated. [Warning: Bit of a negative rant]
Not seeing anything else that's close to photo realistic. I'm hitting the tough bugs first all too often. More than half my time has been spent on ecosystem problems.

Chrome ships WebGPU, a sort-of successor to WebGL. How soon do you see this being adopted by the game dev community?
Yes — and in fact, Firefox's implementation has been the go-to graphics API for folks trying to make Rust gamedev happen for a long time now. Bevy Engine's renderer is built on it, for example.
