bindgen-generated bindings for the statically linked libh3 C library.
h3ron-ndarray

Integration with the ndarray crate to generate H3 cells from raster data (using gdal, ...)
h3ron-graph

Graph algorithms on edges of the H3 spatial indexing system.
h3ron-polars

Integration of the h3 geospatial indexing system with polars dataframes by providing extension traits
to UInt64Chunked
and DataFrame
.
Python bindings
Python bindings for parts of the functionalities are available in the h3ronpy
extension now located in an own repository.
For an overview of some features complementary to libh3 please see the README of the python bindings.
Why this name?
Well, coming up with a good name for a project while avoiding naming conflicts is hard. On the other hand are animal-based names always pretty easy to remember.
How to pronounce it? I got no idea - probably like the heron bird family.
