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?
Not super obscure, but I remember that one specific time when circular-linked-list made a lot of sense to use, well I wanted to use it so I used it.
I had a bunch of API keys with poor expiry documentation and implementation, so to find out if a key expired it had to be used. I put it in a main "keys.pop loop" and all methods below tried to use the key. If HTTP response was (some another obscure HTTP response code like) 505, I simply called `continue;` in the loop to jump to another, without caring at all where I was before.
