impl Clone for AsyncSeekableReaderWriter

fn clone(&self) -> AsyncSeekableReaderWriter

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl IntoPy<Py<PyAny>> for AsyncSeekableReaderWriter

fn into_py(self, py: Python<'_>) -> PyObject

Performs the conversion.

impl PyClass for AsyncSeekableReaderWriter

type Frozen = False

Whether the pyclass is frozen.

impl PyClassImpl for AsyncSeekableReaderWriter

const IS_BASETYPE: bool = false

#[pyclass(subclass)]

const IS_SUBCLASS: bool = false

#[pyclass(extends=…)]

const IS_MAPPING: bool = false

#[pyclass(mapping)]

const IS_SEQUENCE: bool = false

type BaseType = PyAny

Base class

type ThreadChecker = SendablePyClass<AsyncSeekableReaderWriter>

This handles following two situations:

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