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.

Callbacks in embedded | heapless environment
Fixed size function wrappers are not only limited and also a waste of space. Use a configurable function wrapper like fu2 with a stack allocator and set small object optimizer capacity to 0.

A simple std::function alternative that never allocates
std::function wasn't cutting it for me, but I ended up going with fu2::function. It comes with a lot of features (almost too many), but the header size and compile times are comparable to , and it fit my needs pretty well.

Idle: an asynchronous and hot-reloadable C++ dynamic component framework
Thank you, function2 is also used heavily in Idle as a type-erasure backend for continuable that is the primary asynchronous task abstraction.

Orthodox C++
You can write your own std::function, too, nor is it the only STL type that can take a capturing lambda (std::packaged_task for example).
A capturing lambda is just a class with an operator(). It's complicated to do what std::function does, but fully possible.
In fact, custom std::function replacements have better lambda support than std::function itself. Such as unique_function in https://github.com/Naios/function2 which can handle non-copyable lambdas.

Future of embedded coding architecture
What are your thoughts about this CIB library by Intel, https://github.com/intel/compile-time-init-build I am interested to see if this is a generalized and good approach to use compile time polymorphism in MCUs.
