Whether the pyclass is frozen.

impl PyClassBaseType for PyRecordBatch

type LayoutAsBase = PyClassObject<PyRecordBatch>

type BaseNativeType = <PyRecordBatch as PyClassImpl>::BaseNativeType

type Initializer = PyClassInitializer<PyRecordBatch>

type PyClassMutability = <PyRecordBatch as PyClassImpl>::PyClassMutability

impl PyClassImpl for PyRecordBatch

const IS_BASETYPE: bool = true

#[pyclass(subclass)]

const IS_SUBCLASS: bool = false

#[pyclass(extends=…)]

const IS_MAPPING: bool = false

#[pyclass(mapping)]

const IS_SEQUENCE: bool = false

#[pyclass(sequence)]

const IS_IMMUTABLE_TYPE: bool = false

#[pyclass(immutable_type)]

const RAW_DOC: &'static CStr = /// A Python-facing Arrow record batch. /// /// This is a wrapper around a [RecordBatch].

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 BaseType = PyAny

Base class

type ThreadChecker = SendablePyClass<PyRecordBatch>

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.
