ChunkedGeometry into single geometry array

[JosiahParry]

When reading from a geojson file, the geometry is stored into a chunked geometry array. Getting the results into a single array, does not appear to be straight forward. Is there an existing approach to get this done?

here, for example, i can read in a geometry into a Arc<dyn ChunkedGeometryArrayTrait> or use into_inner() to get a Vec<LineStringArray<i32>> but from these, its not clear how to get just a single geometry array or an iterator through single geometries.

use geoarrow::io::geojson::read_geojson;
use geoarrow::array::AsChunkedGeometryArray;
fn main() {
    let f = std::fs::File::open("data/rnet_x.geojson").unwrap();
    let rnet_x = read_geojson(f, None).unwrap();
    let geometry = rnet_x.geometry().unwrap();
    let binding = geometry.as_ref();
    let x = binding.as_line_string();
    let x = x.clone().into_inner();
}

To get an iterator through the individual geometries from the ChunkedGeometryArray I figured I can do:

x
    .chunks()
    .into_iter()
    .map(|xi| xi.iter())
    .flatten();
