Enum geoarrow2::array::geometry::GeometryArray

pub enum GeometryArray<O: OffsetSizeTrait> {
    Point(PointArray),
    LineString(LineStringArray<O>),

A GeometryArray is an enum over the various underlying zero copy GeoArrow array types.

Notably this does not include WKBArray as a variant, because that is not zero-copy to parse.

Variants

LineString(LineStringArray<O>)

Polygon(PolygonArray<O>)

MultiPoint(MultiPointArray<O>)

MultiLineString(MultiLineStringArray<O>)

MultiPolygon(MultiPolygonArray<O>)

impl<'a, O: OffsetSizeTrait> GeometryArrayTrait<'a> for GeometryArray<O>

fn len(&self) -> usize

The length of the GeometryArray. Every array has a length corresponding to the number of geometries it contains.
