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.

Ask HN: What are some 'cool' but obscure data structures you know about?
Succinct Data Structures [0] [1]. It encompass many different underlying data structure types but the overarching idea is that you want small data size while still keeping "big O" run time.
In other words, data structures that effectively reach a 'practical' entropy lower bound while still keeping asymptotic run time.

SDSL-RS: A Rust interface for the C++ Succinct Data Structure Library.
The book mentioned in another comment is probably the best way to go. But FYI, documentation for some data structures include references. An SDSL-lite example can be found here. And its equivalent in SDSL-RS can be found here.

Ask HN: What are some 'cool' but obscure data structures you know about?
Shameless plug, I also maintain an OCaml implementation of egraphs (named ego) at https://github.com/verse-lab/ego
While the most popular implementation at the moment seems to be egg in Rust, I find that OCaml serves as a much more ergonomic environment for quickly prototyping out uses of egraphs in practice. As a bonus, ego also shares the same logical interface as egg itself, so once you've finalised your designs, you shouldn't have much trouble porting them to egg if you need the performance gains.
