Struct WkbViewArray

pub struct WkbViewArray { /* private fields */ }

An immutable array of WKB geometries.

This is stored as an Arrow BinaryViewArray and is semantically equivalent to Vec<Option<Wkb>> due to the internal validity bitmap.

Refer to crate::cast for converting this array to other GeoArrow array types.

Implementations

impl WkbViewArray

pub fn new(array: BinaryViewArray, metadata: Arc<Metadata>) -> Self

fn is_valid(&self, i: usize) -> bool

Returns whether slot i is valid.

impl<'a> GeoArrowArrayAccessor<'a> for WkbViewArray

type Item = Wkb<'a>

The geoarrow scalar object for this geometry array type.

unsafe fn value_unchecked(&'a self, index: usize) -> GeoArrowResult<Self::Item>

Returns the element at index i, not considering validity.
