Struct rustpython_vm::object::PyLease

pub struct PyLease<'a, T: PyObjectPayload> { /* private fields */ }

A borrow of a reference to a Python object. This avoids having clone the PyRef<T>/ PyObjectRef, which isn’t that cheap as that increments the atomic reference counter.

Implementations

impl<'a, T: PyObjectPayload + PyPayload> PyLease<'a, T>

pub fn into_owned(self) -> PyRef<T>

Methods from Deref<Target = PyRef<T>>

pub fn iter(&self) -> impl Iterator<Item = PyRef<PyTraceback>>

Methods from Deref<Target = Py<T>>

pub fn to_attributes( &self, vm: &VirtualMachine ) -> IndexMap<&'static PyStrInterned, PyObjectRef, RandomState>

Take a python dictionary and convert it to attributes.

pub fn get_item_opt<K: DictKey + ?Sized>( &self, key: &K, vm: &VirtualMachine ) -> PyResult<Option<PyObjectRef>>

pub fn get_item<K: DictKey + ?Sized>( &self, key: &K, vm: &VirtualMachine ) -> PyResult

pub fn set_item<K: DictKey + ?Sized>( &self, key: &K, value: PyObjectRef, vm: &VirtualMachine ) -> PyResult<()>

pub fn del_item<K: DictKey + ?Sized>( &self, key: &K, vm: &VirtualMachine ) -> PyResult<()>

pub fn get_chain<K: DictKey + ?Sized>( &self, other: &Self, key: &K, vm: &VirtualMachine ) -> PyResult<Option<PyObjectRef>>

pub fn f_back(&self, vm: &VirtualMachine) -> Option<PyRef<Frame>>

pub fn __init_methods(&self, vm: &VirtualMachine) -> PyResult<()>

pub fn dict(&self) -> PyDictRef

pub fn get_attr<'a>( &self, attr_name: impl AsPyStr<'a>, vm: &VirtualMachine ) -> PyResult

pub fn set_attr<'a>( &self, attr_name: impl AsPyStr<'a>, attr_value: impl Into<PyObjectRef>, vm: &VirtualMachine ) -> PyResult<()>

pub fn fast_issubclass(&self, cls: &impl Borrow<PyObject>) -> bool

Determines if subclass is actually a subclass of cls, this doesn’t call subclasscheck, so only use this if cls is known to have not overridden the base subclasscheck magic method.
