Expand description

Extension methods for all ObjectSubclass impls.

Required Methods§

fn instance(&self) -> BorrowedObject<'_, Self::Type>

Returns the corresponding object instance.

fn from_instance(obj: &Self::Type) -> &Self

Returns the implementation from an instance.

fn obj(&self) -> BorrowedObject<'_, Self::Type>

Returns the corresponding object instance.

Shorter alias for instance().

fn from_obj(obj: &Self::Type) -> &Self

Returns the implementation from an instance.

Shorter alias for from_instance().

fn ref_counted(&self) -> ObjectImplRef<Self>

Returns a new reference-counted wrapper around self.

fn instance_data<U: Any + Send + Sync + 'static>(
&self,
type_: Type
) -> Option<&U>

Returns a pointer to the instance implementation specific data.

This is used for the subclassing infrastructure to store additional instance data.
