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.

Rooting for P1061 "Structured Bindings can introduce a Pack"
This single feature opens a world of new possiblities. For example, it makes implementing "getting the number of fields" trivial. Furthrmore, and much more importantly, it enables turning a struct into a tuple. Currently, this can only be done by enumerating cases (therefore it's not fully generic), as with Boost PFR. By the way, PFR greatly simplifies our codebases, especially for parts with serialization and/or reflection.

Minimum viable declarative GUI in C++
The code is relatively short and can be groked with a few coffees: https://github.com/boostorg/pfr/tree/develop/include/boost/pfr ; if you're using C++17 it uses a binary search (https://github.com/boostorg/pfr/blob/develop/include/boost/pfr/detail/fields_count.hpp) to count the number of fields in a struct, by starting by the observation that a likely majorant on the number of fields in a struct is sizeof(the struct) * CHAR_BIT, assuming not too many [[no_unique_address]] tomfooleries. Then once this count is known it's possible to simply map them as a tuple through sheer brute force and destructuring: https://github.com/boostorg/pfr/blob/develop/include/boost/pfr/detail/core17_generated.hpp

The Serde Rust Framework
I wonder if the c++ approach of boost.pfr would be portable to rust ? It allows reflection on aggregates without needing to annotate anything: https://github.com/boostorg/pfr

Counting the number of fields in an aggregate in C++20
It is an 'interesting' meta-programming problem though (wasted many weeks on it myself, fixed a small gcc bug - a 'uniform init' edge case and filed an issue with magic_get Reflecting array members of aggregate structs).

WASM: Big Deal or Little Deal?
It is what Makepad is working on in an interesting way using Wasm and Rust. They have created a Figma-like DSL and a good code separation with the logic behind it. You can edit UI's of in-production apps, and they are bundling an editor for that. Accessibility is an issue, and the project are looking to offer proper support there. In their video linked on the README they run the conference slides on Makepad with live apps embedded and running at 120 fps.

Snappy UIs with WebAssembly and Web Workers
> if anyone tells you they need to use WebAssembly to make the UI snappy I'd advise you interrogate that assertion thoroughly.
Get prepared to be blown away by Makepad [0]. I have no affiliation with them, but just watched their most recent conference presentation [1]. The slides were made with Makepad itself and included, embedded, a full-blown IDE, a synthesizer app, a Mandelbrod to zoom in endlessly, and more. All running at 120fps. The presentation is for the most part live-coding with this setup.
What they want to do is bring coders and designers closer together, and while some code is in Rust they developed a DSL for the GUI parts that is close to how Figma works. These GUI's can run anywhere.
And I couldn't help thinking "Why would people have complicated stacks to create Web 2.0 apps for the Google Web, when they have this?", in other words an opportunity to break out of the browser straitjacket.

Makepad- Synthesizer Written in Rust
For those who haven’t seen it, Makepad is also an in-browser code editor with an open-source UI toolkit. Looks like this synth is one of the examples of the UI toolkit.

Leveraging Rust and the GPU to render user interfaces at 120 FPS
I tried this, using https://makepad.dev our GPU accelerated UI and renderstack. And unfortunately it wasn't a great experience. Text popping forward for whatever reason is not really an improvement (i tried indent depth, syntax highlighting reasons, cursor behavior). Maybe 'veeeeery' subtly could do something, but otherwise you dont want it to break visual symmetry as we are used to

Wow, so they did: https://github.com/makepad/makepad/pull/142

Rust Web Framework Comparison
We can! It’s a lot of work because you don’t have the whole JS ecosystem to fall back on, but to some that’s a feature not a bug.
My favorite example of this is https://makepad.dev

Why Not Rust?
When it comes to compile times, the most optimized Rust codebase I know for optimized for this is makepad.dev [1].
It is compiling from scratch on mac m1 in around 7.5s [2] and that's +100k lines of Rust. However there is close to none dependencies, so this +100k is all there is to compile pretty much.
