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.

Is there a quadtree implementation with generic types for the coordinates?
Depending on your use case this crate provides a very fast static (must be rebuilt to add/remove bounding boxes) axis aligned bounding box index: https://github.com/jbuckmccready/static_aabb2d_index. It's very fast to build the index using hilbert curve sorting and forms the index structure as a tree with controllable node sizes.

fast_hilbert 2.0.0 released. The fastest hilbert curve converter library written in rust🚀
In general I would have guessed that the code you shared should be faster. It's just a bunch of binary ops. But, I am unable to proof it. Created a branch which contains the func in the benchmarks: https://github.com/becheran/fast-hilbert/tree/cpp_cmp

Efficient Computation of the Hilbert Curve
I (mis)used units tests to generate the LUTs for both directions. Both tests are checked in and available in the sources: gen_lut3_sxxxyyy and gen_lut3_shhh.
