Struct ClassStruct

#[repr(C)]
pub struct ClassStruct<T>
where
    T: ObjectSubclass,
{ /* private fields */ }

A basic class struct that does not store any additional data or virtual methods.

Methods from Deref<Target = Class<<T as ObjectSubclass>::Type>>

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>(&self) -> &Class<U>

where U: IsClass, T: IsA<U>,

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

pub fn upcast_ref_mut<U>(&mut self) -> &mut Class<U>

where U: IsClass, T: IsA<U>,

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

pub fn downcast_ref<U>(&self) -> Option<&Class<U>>

where U: IsClass + IsA<T>,

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 downcast_ref_mut<U>(&mut self) -> Option<&mut Class<U>>

where U: IsClass + IsA<T>,

Casts this class to a mutable 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.
