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.

Hey Rustaceans! Got a question? Ask here! (31/2022)!
Take a look into math libraries, like glam, nalgebra, and cgmath. I've only used these through game engines, though, so I can't offer per-basis reviews/advice.

Any plans for built-in support of Vec2/Vec3/Vec4 in Rust?
But I am writing a Vulkan-based game engine and I use https://crates.io/crates/cgmath extensively. It has vector classes, all the math functions I need, and it even supports a version of swizzling if you activate the feature. Maybe this crate can do what you need?

I want to change my point of view by key input in glium.
There's also a good crate which you can use to quickly create the required matrices called cgmath: https://crates.io/crates/cgmath

Rendering large 3D tilemaps with a single draw call at 3000 FPS
One great thing about Rust is that the library ecosystem is surprisingly mature, especially considering how young the language is (1.0 was released in 2015). C# also has good libraries, but from my experience it's kinda fiddly to use most open source libraries with Unity, at least without modifications. Rust's ecosystem has some excellent libraries that help with game development, such as noise for procedural generation and cgmath for linear algebra.

Let's thank who have helped us in the Rust Community together!
Jubilee and Caleb Zulawski for their tireless work on the portable SIMD project. It will land, some day, and when it does it's going to be an amazing boon for the project.

Mutually aligned vectors?
The portable SIMD project implements an as_simd() function for slices. The basics are that you get 3 slices and the middle one is a SIMD slice. It allows for fast aligned loads of the data, which could matter if your algorithm is becoming memory bound; it is also a convenient and safe abstraction. In my case, I actually have 2 vectors (say, x and y). I can take them apart using as_simd() like so:

Zen4's AVX512 Teardown
This Rust issue [0] was the best short summary of what an SIMD Shuffle is I could find:
„A "shuffle", in SIMD terms, takes a SIMD vector (or possibly two vectors) and a pattern of source lane indexes (usually as an immediate), and then produces a new SIMD vector where the output is the source lane values in the pattern given.“

possibility of blas natively in Rust
Yet by default it generates code which is only compatible with Pentium4 or newer. In fact lots of serious issues relate to older CPUs and rustc developers plan is to declare them closed when they would be able to drop i686 support (all AMD CPUs which support SSE2 support x86-64, too while Intel situation is mess).

Best portable simd library for stable rust?
The standard API crate for portable simd is at https://github.com/rust-lang/portable-simd, but using this requires nightly, which I don't want to do. I'd like to use a crate for simd that works on both x86_64 and wasm in stable rust. wide looks fine for this purpose. Are there any potentially better choices?
