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.

Rust Game Physics Engines: PhysX, Rapier, XPBD & Others
Some other Rust game engines ship with their own physics engine. Fyrox, for example, has advanced 2D/3D physics, supporting rigid bodies, joints, ray casting and more. Godot too, which has community-led Rust bindings also has an in-built physics engine as well as a Godot-native extension using the Jolt physics engine. In fact, which is reported to be more performant than the official physics engine.

“This Is a Disaster:” Game Developers Scramble to Deal with Unity’s New Fees
I would say Bevy isn't really similar to Unity. Something like Fyrox - https://fyrox.rs/ - would be more similar. Bevy is more low level and lacks an editor (as of now, it's planned)

Help me find my game engine!
Fyrox might be an option, but for what you're looking (simple game logic, low performance concerns, desire for complete editor) for I'd probably choose Godot over it.

What is Rust's potential in game development?
Besides Bevy there’s also Fyrox Engine that looks very promising. https://fyrox.rs/

NANOVOID Devlog #1: Lua Scripting
We have our own engine. There aren't really full engines available in the Rust ecosystem. Bevy attempts to fill this, but it's far from being feature complete. There's also https://fyrox.rs/, but that's also work in progress. There's also https://rend3.rs/ which is just a 3d renderer, so you'll need to build the rest of the engine yourself.

I was wrong about rust ... The convenience of cargo being the main reason... I'm going all in on rust now, I leave cpp with a heavy heart.

I learned to love testing game code
Wow... Okay. I see you didn't even bother watching the video in full. But, I'll respond in case your misinformed comment manages to deter people from watching it.
You somehow managed to ignore all the points of the talk. Like literally every one of them, and I'm not even exaggerating. And then you somehow both managed to focused on irrelevant details and to talk out of your ass (like, at least be right about the details?), all to make a tangential point about how "sUpErIoRlY sMaRt CpP dEvs ArE" because they know this really basic shit.
Let's start.
First you talk about "borrow checker issues" she's demonstrating in the OOO design. The point here was to illustrate the amount of coupling and "explosion" in size with this approach. The point was "OOO is probably not a good design paradigm for game dev". Then she continues how Rust surfaces this bad design paradigm much earlier than it would've happened in other languages/ecosystems. That's all.
More, what you call a custom allocator with tombstoning/generations are just things that exist with a lot of ECS implementations (regardless of language), and it's just become "tribal wisdom" at this point that this table-esque storage backend work really well with ECS (I dunno which one came first; older game devs might know more about ECS history/evolution than I do).
Also not sure what you mean by "that can fail in most of the typical ways and that she's gained nothing over the cpp implementation while wasting effort to force Rust into allowing her to do something really basic"... Maybe I misunderstand what you mean, but it sounds to me like you're comparing working with `Option` as being the same failure mode as working with `void`. That's just utterly ludicrous nonsense.
Her ECS implementation is... Well, it was made to fit inside a few slides for a 40-minute talk. So, yeah it's not great; there's plenty of small issues with it, but none of them are with Rust, or with ECS itself... Did you expect a production ready ECS library you can copy off of slides and use them in your next game, lol? If anything, her implementation has too much passing resemblance with what a C++ implementation would look like (which is something she's very familiar with and her starting point) than a Rust one. So, I'm just bewildered why this is the bone you decided to pick.
If you're interested in what a production-ish ECS implementation in Rust looks like, check out Amethyst's Legion or Bevy's ECS. Although, Bevy takes takes ECS a few... staircases (rather than steps) further with its own ECS. I really* encourage everyone to read up on Bevy's ECS and check out the unofficial Bevy cheatsheet book; I'm certain at leat UE game devs will know how to appreciate how beautiful and ergonomic the design is, but others should as well). Aside: her ECS implementation is still safer than most C/C++ implementations used in published games, but that's a bit besides the point since that's the borrow checker doing its job.
Anyway, the irony is that she much better explains the pitfalls of her own implementation details that you do and she also explains why they're "fine" sometimes. And it was kinda implied that it's fine (from what I remember) because it's no worse than what you end up doing in C++ or Java when implementing ECS, but at least it's safe in Rust. She acknowledges that there's probably better ways to do it.

New to Game Dev
Development on Amethyst (the engine) stopped, the Amethyst Foundation is now focusing on developing engine agnostic tools, like Legion and Distill

What's the state of Legion ECS development at the end of 2021?
Though, Legion Github was not too active during this year, and with the recent shutdown repurpose of Amethyst Foundation its future looks even less promising.

Why can't you have fields as traits in Rust?
Take a look at legion on how to compose data objects in Rust.

rust ECS that can register new component types at runtime?
I'm trying to avoid that architecture even though that's the path of least resistance to work with existing ECS libs in rust.This discussion about FFI for legion touches on what I'm trying to accomplish. They use a u32 as a custom type ID to deal with the FFI boundary. The size param would be for each instance of that registered component, so the Vec wouldn't have knowledge of the size of each component (which might be 16 bytes for example). Ideally, components and systems defined in the scripting language are more 'first class' instead of scripts only being invoked by entities with a DynamicComponent. This discussion is very helpful btw, I appreciate your thoughts

bracket-lib: a few discussion items
I ended up with my own, a bit ugly, code. I'll quote it here, because even deserializing a JSON into Legion components is not 100% trivial task. Someone else filed an issue 268 in Legion, I have filed another one too.

Unity patents "Methods and apparatuses to improve [..] an Entity Component System (ECS)"
Bevy was introduced in 2020 and the patent was filed in 2018. I don't think any of the ECS mentioned predate the patent filing (looks like legion introduced this model in 2019), so it's not as derivative as it seems in the current landscape.

4MB Jam - You have a month to make a game that fits into 4 Megabytes! (No theme)
I have been working on a game using Rust, SDL2 and Legion. I statically link SDL2, which mean that only the parts that I actually use gets included. Also i have been using the include_bytes to include my assets. This creates a single executable that is around 3mb (this is without compiler optimizing for size, it could go lower at the cost of runtime speed). Running (upx)https://github.com/upx/upx on it, it comes out to about 900kb.
