List of cells to GeoArrow Polygon Array

[kylebarron]

I'm interested in potentially using h3ronpy from Lonboard, a Python library I develop for fast geospatial visualization in deck.gl. One of the ways I'd like to support visualizing H3 data is by converting the H3 cells to polygons, and then rendering those polygons. (See also xarray-contrib/xdggs#67) The h3-py function h3_to_geo is not vectorized, and so is very slow.

I know you have https://github.com/nmandery/h3ronpy/blob/f9176e039821a9ed834f8f83ab5b65f9a1e144bc/crates/h3arrow/src/array/to_geoarrow.rs; is that exported to the Python API yet?

This part is not yet available to python yet. I thought about using https://github.com/geoarrow/geoarrow-rs/tree/main/python/pyo3-geoarrow to avoid having to implement the conversions myself, but noticed it is not available on crates.io. Do you plan to publish it?

Just published geoarrow v0.4.0-beta.1 and pyo3-geoarrow v0.1.0-beta.1.

Would like to publish stable versions in the next week or two but need to clean up some things first.
