Struct PyGeoChunkedArray 

pub struct PyGeoChunkedArray { /* private fields */ }

Python wrapper for a chunked GeoArrow geometry array.

A chunked array is a collection of contiguous arrays of the same type.

Implementations

impl PyGeoChunkedArray

pub fn try_new( chunks: Vec<Arc<dyn GeoArrowArray>>, data_type: GeoArrowType, ) -> PyResult<Self>

Construct a new PyGeoChunkedArray from existing chunks and a field.

pub fn from_arrow_pycapsule( capsule: &Bound<'_, PyCapsule>, ) -> PyGeoArrowResult<Self>

Import from a raw Arrow C Stream capsule

pub fn to_geoarrow<'py>( &'py self, py: Python<'py>, ) -> PyResult<Bound<'py, PyAny>>

Export to a geoarrow.rust.core.GeometryArray.

This requires that you depend on geoarrow-rust-core from your Python package.

pub fn from_arrays( chunks: Vec<Arc<dyn GeoArrowArray>>, ) -> PyGeoArrowResult<Self>

Create a new PyChunkedArray from a vec of ArrayRefs, inferring their data type automatically.

pub fn into_inner(self) -> (Vec<Arc<dyn GeoArrowArray>>, GeoArrowType)

Consume this wrapper and return the underlying chunks and data type.

impl PyClassImpl for PyGeoChunkedArray

const MODULE: Option<&str>

Module which the class will be associated with.

const IS_BASETYPE: bool = true

#[pyclass(subclass)]

const IS_SUBCLASS: bool = false

#[pyclass(extends=…)]

const IS_MAPPING: bool = false

#[pyclass(mapping)]

const RAW_DOC: &'static CStr = /// Python wrapper for a chunked GeoArrow geometry array. /// /// A chunked array is a collection of contiguous arrays of the same type.

Docstring for the class provided on the struct or enum.

const DOC: &'static CStr

Fully rendered class doc, including the text_signature if a constructor is defined.

type Layout = <<PyGeoChunkedArray as PyClassImpl>::BaseNativeType as PyClassBaseType>::Layout<PyGeoChunkedArray>

Description of how this class is laid out in memory

type BaseType = PyAny

Base class

type ThreadChecker = NoopThreadChecker

This handles following two situations:

type PyClassMutability = <<PyAny as PyClassBaseType>::PyClassMutability as PyClassMutability>::ImmutableChild

Immutable or mutable

type Dict = PyClassDummySlot

Specify this class has #[pyclass(dict)] or not.

type WeakRef = PyClassDummySlot

Specify this class has #[pyclass(weakref)] or not.

type BaseNativeType = PyAny

The closest native ancestor. This is PyAny by default, and when you declare #[pyclass(extends=PyDict)], it’s PyDict.

fn items_iter() -> PyClassItemsIter

fn lazy_type_object() -> &'static LazyTypeObject<Self>

fn dict_offset() -> Option<PyObjectOffset>

Used to provide the dictoffset slot (equivalent to tp_dictoffset)

fn weaklist_offset() -> Option<PyObjectOffset>

Used to provide the weaklistoffset slot (equivalent to tp_weaklistoffset

impl PyClassNewTextSignature for PyGeoChunkedArray

const TEXT_SIGNATURE: &'static str = "(arrays, type=None)"
