Struct WkbBuilder

pub struct WkbBuilder<O: OffsetSizeTrait>(/* private fields */);

The GeoArrow equivalent to Vec<Option<Wkb>>: a mutable collection of Wkb buffers.

Converting a WkbBuilder into a GenericWkbArray is O(1).

Implementations

impl<O: OffsetSizeTrait> WkbBuilder<O>

pub fn new(typ: WkbType) -> Self

Creates a new empty WkbBuilder.

pub fn with_capacity(typ: WkbType, capacity: WkbCapacity) -> Self

Initializes a new WkbBuilder with a pre-allocated capacity of slots and values.

pub fn push_geometry(&mut self, geom: Option<&impl GeometryTrait<T = f64>>)

Push a Geometry onto the end of this builder

pub fn extend_from_iter<'a>( &mut self, geoms: impl Iterator<Item = Option<&'a (impl GeometryTrait<T = f64> + 'a)>>, )

Extend this builder from an iterator of Geometries.

pub fn from_nullable_geometries( geoms: &[Option<impl GeometryTrait<T = f64>>], typ: WkbType, ) -> Self

Create this builder from a slice of nullable Geometries.

pub fn finish(self) -> GenericWkbArray<O>

Consume this builder and convert to a GenericWkbArray.

This is O(1).
