Struct PyMapping

Source

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

Expand description

Represents a reference to a Python object supporting the mapping protocol.

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

For APIs available on mapping objects, see the PyMappingMethods trait which is implemented for Bound<'py, PyMapping>.

Implementations§

Source §

impl PyMapping

Source

pub fn register<T: PyTypeInfo>(py: Python<'_>) -> PyResult<()>

Register a pyclass as a subclass of collections.abc.Mapping (from the Python standard library). This is equivalent to collections.abc.Mapping.register(T) in Python. This registration is required for a pyclass to be downcastable from PyAny to PyMapping.
