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.

Refactoring with C++17 std::optional
Or nonstd::expected. Personally, I would rather use output parameters and an enum result or a std::variant over std::optional, because at the very least you have the option for more specific error diagnostics.

std::expected (with monadic interface) implementation in C++20 (P0323, P2505)
As someone who is new to this API (so I can't discern from the list of features which might be better for my use case), I second the question, and I'd like to extend the question to how it compares to https://github.com/martinmoene/expected-lite and https://github.com/bitwizeshift/result as well.

C++ Return: std::any, std::optional, or std::variant?

Real-world examples of std::expected in codebases?
Example of other people trying to do it in a generic way, as a separate library (instead of in the utility part of some bigger codebase): - https://github.com/bitwizeshift/result - https://github.com/oktal/result - https://github.com/basicpp17/result17 - https://github.com/p-ranav/result
