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.

placing pixels
Well, it depends on how you use it; writing to an image buffer isn't much less efficient than writing to any normal buffer (in fact, although displaying your scene to a window efficiently is important, your main bottleneck will be the actual ray tracing loop). You may want to read this article for a practical example of using an ImageBuffer to create and draw a texture with Piston. Other window backends you could use, apart from pixels which was already mentioned in another comment, include minifb and Mini GL, though I haven't personally used them.

Ways to create game engines
And I really like generic systems where you can create a lot of different things. A program that interested me is Piston (https://github.com/PistonDevelopers/piston), I haven't researched it in depth yet, but the concept of being able to create several things with a base and different modules is very interesting

Really frustrated. [Warning: Bit of a negative rant]

What would be best for a 2D only game? Piston, Bevy, or Fyrox?
I haven't seen too much on Piston. No idea how active or recent these projects are but I'm still interested in working with it.
-
I made my first GL project using Piston.
Check out their homepage, https://piston.rs, they even show off some great examples of how their library has been used!

Emulating the Sega Genesis - Part II
Before I could implement the display output, I needed something to draw the images onto. There are quite a few Rust crates available to create a GUI window and update it with 2D graphics. Most of these are of course intended for making games, and also include ways of getting key presses as input, which I'll also need. I looked at Piston, which I've used before on other projects, Macroquad, which also supports web assembly as well as desktop targets, Pixels, which is intended specifically for 2D games, and Minifb, which is also specifically for 2D applications, but is much simpler. I also tried out libretro, which is specifically made for video game emulation, but I found it much more restrictive than the others because of it's narrow focus.

I'm a "low-level, terminal-only" kind of developer, completely new to the game dev world. I've been working on a 2D platformer in my spare time. Can you explain to me what I'm missing out on, by not using a "game engine"?
Depends on my goals. I year ago I wanted to learn rust, so I used piston for a gamejam. (There are several rust engines including bevy, piston, amethyst. They probably vary in quality, features, and constraints.) Piston was a terrible experience because compilation is slow even on that tiny project.

Beginner looking for code review : my ECS lib !
For further reading, here is a great article about these different approaches within Rust specifically: https://csherratt.github.io/blog/posts/specs-and-legion/ and here is a great general resource for commonly-used terms and techniques in ECS development: https://github.com/SanderMertens/ecs-faq

Ways to create game engines
Godot has a node based system (nodes can have child nodes linked to them, and there are different types of nodes for the type of functionality they represent). Another alternative could be a more OOP approach (utilising inheritance as the main means of extending functionality), not aware of any modern engines that take this approach anymore. It’s also worth noting that ECS implementations can differ wildly, this faq from the flecs creator has a good rundown on what some of different variants are.

Is ECS really the way to go in C++?
You might wanna take a look at https://github.com/SanderMertens/ecs-faq, it lays this all out better than I can.

Functional relational programming model in Clojure(Script)
Using the relational model for app data in memory is really interesting.
Martin Fowler wrote about doing that as a way to get around the "object-relational mismatch" issue[1]. Richard Fabian describes "data-oriented design" as having a lot of overlap with the relational model[2]. ECSes becoming very popular in game engines are basically in-memory relational databases where "components" are "tables"[3].

What are some things you have used ECS for?
While Unity's DOTS/ECS is positioned as solving performance issues for large numbers of objects, there are a number of other advantages. See https://github.com/SanderMertens/ecs-faq for a more in-depth look. IMHO the reusability and extensibility ECS encourages is as valuable as any performance increase. Compared to the GameObject style, which encourages random state mutations and side-effects, ECS enforces a more functional style, which results in code that is easier to reason about and test.
