Struct PyGenericAlias 

pub struct PyGenericAlias(/* private fields */);

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.

Implementations

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.

Trait Implementations

impl PyTypeInfo for PyGenericAlias

const NAME: &'static str = "PyGenericAlias"

Class name.

const MODULE: Option<&'static str>
