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.

What C++ library do you wish existed but hasn’t been created yet?
I'm not sure this is quite what you're asking for, but this library has been super helpful to me in the past : https://github.com/Neargye/magic_enum

Also, a shoutout to Magic Enum: https://github.com/Neargye/magic_enum
- Favorite Ways of Stringifying Enums
-
enum_name (yet another enum to/from string conversion utility >=C++11)
What does this have to offer over magic_enum?
-
quill v2.7.0 released - Asynchronous Low Latency C++ Logging Library
But it's a hack, and I prefer not to use hacks in production, because of their significant limitations:
-
Enums print numbers instead of words
You can either write a to string(view) function for your enum or use https://github.com/Neargye/magic_enum
-
Enums with methods
Why reinvent the wheel? magic_enum
-
Error: Boost bimap can't convert const CompatibleKey to Key&
Also if you want to convert enum members to string representation I suggest you just use magic_enum instead, much smaller dependency.
-
Macro to write enum and converter from and to string
Magic Enum provides that.

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).
