Trait Implementations

impl Clone for PyJoinConstraint

fn clone(&self) -> PyJoinConstraint

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PyJoinConstraint

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl From<JoinConstraint> for PyJoinConstraint

fn from(join_constraint: JoinConstraint) -> PyJoinConstraint

Converts to this type from the input type.

impl From<PyJoinConstraint> for JoinConstraint

fn from(join_constraint: PyJoinConstraint) -> Self

Converts to this type from the input type.

impl IntoPy<Py<PyAny>> for PyJoinConstraint

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

Performs the conversion.

impl PyClass for PyJoinConstraint

type Frozen = False

Whether the pyclass is frozen.

impl PyClassImpl for PyJoinConstraint

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

#[pyclass(sequence)]

type Layout = PyCell<PyJoinConstraint>

Layout

type BaseType = PyAny

Base class

type ThreadChecker = ThreadCheckerStub<PyJoinConstraint>

This handles following two situations:

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

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 doc(py: Python<'_>) -> PyResult<&'static CStr>

Rendered class doc

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

fn dict_offset() -> Option<isize>

fn weaklist_offset() -> Option<isize>

impl<'a, 'py> PyFunctionArgument<'a, 'py> for &'a PyJoinConstraint

type Holder = Option<PyRef<'py, PyJoinConstraint>>

fn extract(obj: &'py PyAny, holder: &'a mut Self::Holder) -> PyResult<Self>

impl<'a, 'py> PyFunctionArgument<'a, 'py> for &'a mut PyJoinConstraint

type Holder = Option<PyRefMut<'py, PyJoinConstraint>>

fn extract(obj: &'py PyAny, holder: &'a mut Self::Holder) -> PyResult<Self>

impl PyTypeInfo for PyJoinConstraint

type AsRefTarget = PyCell<PyJoinConstraint>

Utility type to make Py::as_ref work.

const NAME: &'static str = _

Class name.

const MODULE: Option<&'static str> = _

Module name, if any.

fn type_object_raw(py: Python<'_>) -> *mut PyTypeObject

Returns the PyTypeObject instance for this type.

fn type_object(py: Python<'_>) -> &PyType

Returns the safe abstraction over the type object.

fn is_type_of(object: &PyAny) -> bool

Checks if object is an instance of this type or a subclass of this type.

fn is_exact_type_of(object: &PyAny) -> bool

Checks if object is an instance of this type.
