Struct pyo3::PyFrozenSet

pub struct PyFrozenSet(_);

Represents a Python frozenset

Methods

impl PyFrozenSet

fn new<T: ToPyObject>(py: Python, elements: &[T]) -> Py<PyFrozenSet>

Creates a new frozenset.

May panic when running out of memory.

fn len(&self) -> usize

Return the number of items in the set. This is equivalent to len(p) on a set.

fn contains<K>(&self, key: K) -> PyResult<bool> where
    K: ToBorrowedObject, 

Determine if the set contains the specified key. This is equivalent to the Python expression key in self.

Trait Implementations

impl AsRef<PyObjectRef> for PyFrozenSet

fn as_ref(&self) -> &PyObjectRef

Performs the conversion.

impl PyObjectWithToken for PyFrozenSet

fn py(&self) -> Python

impl ToPyPointer for PyFrozenSet

fn as_ptr(&self) -> *mut PyObject

Gets the underlying FFI pointer, returns a borrowed pointer.

impl PartialEq for PyFrozenSet

fn eq(&self, o: &PyFrozenSet) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=.

impl PyTypeInfo for PyFrozenSet

type Type = ()

type BaseType = PyObjectRef

Base class

const NAME: &'static str

NAME: &'static str = "PyFrozenSet"

const SIZE: usize

SIZE: usize = ::std::mem::size_of::<::ffi::PyObject>()

Size of the rust PyObject structure (PyObject + rust structure)

const OFFSET: isize

OFFSET: isize = 0

Type instance offset inside PyObject structure

unsafe fn type_object() -> &'static mut PyTypeObject

PyTypeObject instance for this type

fn is_instance(ptr: *mut PyObject) -> bool

Check if *mut ffi::PyObject is instance of this type

const DESCRIPTION: &'static str

DESCRIPTION: &'static str = "\u{0}"

Class doc string

const FLAGS: usize

FLAGS: usize = 0

Type flags (ie PY_TYPE_FLAG_GC, PY_TYPE_FLAG_WEAKREF)

fn is_exact_instance(ptr: *mut PyObject) -> bool

Check if *mut ffi::PyObject is exact instance of this type

impl PyTypeObject for PyFrozenSet

fn init_type()

Initialize type object

fn type_object() -> Py<PyType>

Retrieves the type object for this Python object type.

fn create(py: Python) -> PyResult<PyRawObject> where
    Self: Sized + PyObjectAlloc<Self> + PyTypeInfo, 

Create PyRawObject which can be initialized with rust value

impl ToPyObject for PyFrozenSet

fn to_object(&self, py: Python) -> PyObject

Converts self into a Python object.

impl ToBorrowedObject for PyFrozenSet

fn with_borrowed_ptr<F, R>(&self, _py: Python, f: F) -> R where
    F: FnOnce(*mut PyObject) -> R, 

Converts self into a Python object and calls the specified closure on the native FFI pointer underlying the Python object.

impl Debug for PyFrozenSet

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

Formats the value using the given formatter.

impl Display for PyFrozenSet

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

Formats the value using the given formatter.

impl<'a> FromPyObject<'a> for &'a PyFrozenSet

fn extract(ob: &'a PyObjectRef) -> PyResult<Self>

Extracts Self from the source PyObject.
