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.

We have getrandom at home
Making compatibility promises for distributions means they cannot take advantage of potential advancements in the field.

Blog Post: On Random Numbers
Defining an error type that is meaningful, portable, and compatible with no-std isn't straightforward. If the std lib's getrandom requires std, then just like that, rand and many other crates won't use it anyway. Using io::Result seems to me to face this challenge.

Hey Rustaceans! Got a question? Ask here (52/2022)!
Some wasm targets can’t generate random numbers at all but in the case of the book because you are using wasm in a browser you can use JS to generate random numbers. I believe there’s a way to get the rand crate to use JS as the backend for generating rand but its a bit more convoluted than the easy one-liner that the book suggests.

[Media] Nebulabrot rendered with Rust — Explanations in the comments
This uses rand and xcomplex to handle the mathematics, png to write image files, and dialoguer and indicatif for some pretty prompts and progress bars.

Do you ever use unsafe { .. } when not implementing custom data structures or interacting with external C code?
You can often achieve this without any unsafe by putting an assert!() on the length before the hot loop. For example, I got rid of some unsafe in rand that way.

Original source of `(seed * 9301 and 49297) % 233280` random algorithm?
This is a widely used method to map random integers to floating point numbers, but it has the disadvantage of wasting 1 bit of float mantissa precision.
On modern CPUs, its computational advantage over full-precision mapping methods, such as multiplication by a float, is not always clear [1].

Any plans for built-in support of Vec2/Vec3/Vec4 in Rust?
In fact, there are a lot of crates in Rust where in other programming languages, it would be included in the standard library. Examples are regex, random number generators, additional iterator methods, macros for other collections, num traits, loggers, HTTP libraries, error handling, async runtimes, serialization and deserialization, date and time, and many more.
