Struct PyGenericAlias 

#[repr(transparent)]
pub struct PyGenericAlias(PyAny);

Available on Py_3_9 only.

Represents a Python types.GenericAlias object.

Values of this type are accessed via PyO3’s smart pointers, e.g. as Py<PyGenericAlias> or Bound<'py, PyGenericAlias>.

This type is particularly convenient for users implementing __class_getitem__ for PyO3 classes to allow runtime parameterization.

#[doc(hidden)]

pub const _PYO3_INTROSPECTION_ID: &'static str = ":: core :: option :: Option :: Some(\"builtins\")PyGenericAlias"

impl PyGenericAlias

pub fn new<'py>( py: Python<'py>, origin: &Bound<'py, PyAny>, args: &Bound<'py, PyAny>, ) -> PyResult<Bound<'py, PyGenericAlias>>

Creates a new Python GenericAlias object.

origin should be a non-parameterized generic class. args should be a tuple (possibly of length 1) of types which parameterize origin.

const TYPE_HINT: PyStaticExpr

Available on crate feature experimental-inspect only.

Provides the full python type as a type hint.

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

Returns the PyTypeObject instance for this type.

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

Returns the safe abstraction over the type object.

fn is_type_of(object: &Bound<'_, PyAny>) -> bool

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

fn is_exact_type_of(object: &Bound<'_, PyAny>) -> bool

Checks if object is an instance of this type.
