Trait PyTypeInfo 

pub unsafe trait PyTypeInfo: Sized {
    const NAME: &'static str;
    const MODULE: Option<&'static str>;
    const TYPE_HINT: TypeHint = _;

    // Required method
    fn type_object_raw(py: Python<'_>) -> *mut PyTypeObject;

    // Provided methods
    fn type_object(py: Python<'_>) -> Bound<'_, PyType> { ... }
    fn is_type_of(object: &Bound<'_, PyAny>) -> bool { ... }
    fn is_exact_type_of(object: &Bound<'_, PyAny>) -> bool { ... }
}

Python type information. All Python native types (e.g., PyDict) and #[pyclass] structs implement this trait.

This trait is marked unsafe because:

• specifying the incorrect layout can lead to memory errors
• the return value of type_object must always point to the same PyTypeObject instance

It is safely implemented by the pyclass macro.

Safety

Implementations must provide an implementation for type_object_raw which infallibly produces a non-null pointer to the corresponding Python type object.

is_type_of must only return true for objects which can safely be treated as instances of Self.

is_exact_type_of must only return true for objects whose type is exactly Self.

Required Associated Constants

const NAME: &'static str

👎Deprecated since 0.28.0: prefer using ::type_object(py).name() to get the correct runtime value

Class name.

const MODULE: Option<&'static str>

👎Deprecated since 0.28.0: prefer using ::type_object(py).module() to get the correct runtime value

Module name, if any.

Provided Associated Constants

const TYPE_HINT: TypeHint = _

Provides the full python type as a type hint.

Required Methods

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

Returns the PyTypeObject instance for this type.

Provided Methods

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.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
