Our great sponsors
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.

- DynaMix 2.0.0 Released
-
rust-like traits on plain C++ with short macro (type erasure actually)
https://github.com/kelbon/AnyAny trait(add, void(int), self.add(args...));
-
Static Interfaces, concepts vs de-virtualisation?
i dont know what he means, but with this type erasure library you can have non virtual interface and still use dynamic polymorphism with those types, so you dont need choose *do i need to do this type polymorphic* etc
-
[C++23] constexpr std::function in 40 LOC (simplified) powered by constexpr std::unique_ptr
There are also invoking from tuple and curring (just an example of technique)https://github.com/kelbon/AnyAny/blob/main/examples/functional_paradigm.hpp

A call to action: Think seriously about “safety”; then do something sensible about it -> Bjarne Stroustrup
As for my example containers: https://github.com/kelbon/AnyAny/blob/main/include/data_parallel_vector.hpp

С++20 library for high-performance polymorphic types usage
variant_swarm - container which behaves as set of std::variant, but with much faster visit operation and operation for getting view to all values of type T. It short, it just stores all types separatelly and supports operations visit, view, also you can change underlying containers for Ts..., it is std::vector by default https://github.com/kelbon/AnyAny/blob/main/include/variant_swarm.hpp

I wrote multidispatching(runtime overload resolution) in C++ (and its not std::variant)
Its part of my library for working with polymorphic types.
-
I wrote a library that emulates dyn traits from Rust in C++
Good idea selling Rust from behind enemy lines soldier! My god, your readme doesn't even mention Rust, wonderful!

Using final in C++ to improve performance
https://github.com/kelbon/AnyAny here you can see how it implemented, for example

Type Erasure in C++ Explained
And if it were in the standard there wouldn't be at least five well known libraries implementing it (including from Adobe and from Facebook): https://github.com/boost-ext/te#similar-libraries
As far as I know (I don't really follow the committee work) the latest attempt to introduce run-time duck-typing in the standard was https://github.com/andyprowl/virtual-concepts, which seems dead.
What are some alternatives?
tolc - A bindings compiler for C++
dyno - Runtime polymorphism done right
entt - Gaming meets modern C++ - a fast and reliable entity component system (ECS) and much more
Kalman - Kalman Filter
actix-net - A collection of lower-level libraries for composable network services.
tinyformat - Minimal, type safe printf replacement library for C++
glaze - Extremely fast, in memory, JSON and interface library for modern C++
kelcoro - C++20 coroutine library
azula - A fast, statically typed compiled language
ReactivePlusPlus - Implementation of async observable/observer (Reactive Programming) in C++ with care about performance and templates in mind in ReactiveX approach
hsm - Finite state machine library based on the boost hana meta programming library. It follows the principles of the boost msm and boost sml libraries, but tries to reduce own complex meta programming code to a minimum.
