Struct rustpython_vm::object::PyRefExact

#[repr(transparent)]
pub struct PyRefExact<T: PyObjectPayload> { /* private fields */ }

PyRef but guaranteed not to be a subtype instance

Implementations

impl<T: PyObjectPayload> PyRefExact<T>

pub unsafe fn new_unchecked(obj: PyRef<T>) -> Self

Safety

obj must have exact type for the payload

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

Methods from Deref<Target = Py<T>>

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

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.
