Struct ClassRef

pub struct ClassRef<'a, T: IsClass>(/* private fields */);

Reference to the class struct of type T.

Methods from Deref<Target = Class<T>>

pub fn type_(&self) -> Type

Get the type id for this class.

This is not equivalent to T::static_type() but is the type of the subclass of T where this class belongs to.

pub fn upcast_ref<U: IsClass>(&self) -> &Class<U>

where T: IsA<U>,

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

pub fn downcast_ref<U: IsClass + IsA<T>>(&self) -> Option<&Class<U>>

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

pub fn parent(&self) -> Option<ClassRef<'_, T>>

Gets the parent class struct, if any.
