Provided methods

`fn get_type(&self) -> Type`

Get the type id for this class.

`fn upcast_ref<U>(&self) -> &U where U: IsClassFor, Self::Instance: IsA<<U as IsClassFor>::Instance>, <U as IsClassFor>::Instance: ObjectType,`

Casts this class to a reference to a parent type's class.

`fn upcast_ref_mut<U>(&mut self) -> &mut U where U: IsClassFor, Self::Instance: IsA<<U as IsClassFor>::Instance>, <U as IsClassFor>::Instance: ObjectType,`

Casts this class to a mutable reference to a parent type's class.

`fn downcast_ref<U>(&self) -> Option<&U> where U: IsClassFor, <U as IsClassFor>::Instance: IsA<Self::Instance>, Self::Instance: ObjectType,`

Casts this class to a reference to a child type's class or fails if this class is not implementing the child class.

`fn downcast_ref_mut<U>(&mut self) -> Option<&mut U> where U: IsClassFor, <U as IsClassFor>::Instance: IsA<Self::Instance>, Self::Instance: ObjectType,`

Casts this class to a mutable reference to a child type's class or fails if this class is not implementing the child class.

`fn from_type(type_: Type) -> Option<ClassRef<Self>>`

Gets the class struct corresponding to type_.

This will return None if type_ is not a subclass of Self.
