Type Definition rustpython_vm::obj::objdict::PyDictRef

type PyDictRef = PyRef<PyDict>;

Methods

impl PyDictRef

pub fn copy(self) -> PyDict

pub fn to_attributes(self) -> PyAttributes

Take a python dictionary and convert it to attributes.

pub fn from_attributes(
    attrs: PyAttributes,
    vm: &VirtualMachine
) -> PyResult<Self>

pub fn contains_key<T: IntoPyObject>(&self, key: T, vm: &VirtualMachine) -> bool

pub fn size(&self) -> DictSize

pub fn get_item_option<T: IntoPyObject + DictKey + Copy>(
    &self,
    key: T,
    vm: &VirtualMachine
) -> PyResult<Option<PyObjectRef>>

This function can be used to get an item without raising the KeyError, so we can simply check upon the result being Some python value, or None. Note that we can pass any type which implements the DictKey trait. Notable examples are String and PyObjectRef.

Trait Implementations

impl IntoIterator for PyDictRef

type Item = (PyObjectRef, PyObjectRef)

The type of the elements being iterated over.

type IntoIter = DictIter

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl<'_> IntoIterator for &'_ PyDictRef

type Item = (PyObjectRef, PyObjectRef)

The type of the elements being iterated over.

type IntoIter = DictIter

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.
