[ANN] - An Harder, Better, Faster, Stronger version of Uber's H3 in Rust

A month has passed since I've gained some unsolicited free time... so I've used it to work on this little project I had in mind for a while.

And it's now ready for prime time.

The Hydronium Project is mainly a rewrite of the H3 library in Rust, featuring a nice perf boost (2-digit speedup in some cases) for several core functions. It also comes with:

• bells and whistles (e.g. GeoJSON support, compatibility with the geo crate, ...)
• a convenient CLI to quickly test ideas and process data directly from the terminal
• an H3-compatible C API to ease the adoption
• a novel compression algorithm tailored for H3 cell indexes

If you wanna know more, you can go read this article which goes into more detail.

Last but not least: kudos to the H3 devs!

The rewrite has been a breeze thanks to the exemplary state of their codebase: good code, well-documented, and duly tested. It was a pleasure to dive in.
