[−][src]Struct vtable::VWeak
Weak pointer for the VRc where VTable is a VTable struct, and
X is the type of the instance, or Dyn if it is not known
Similar to std::rc::Weak.
Can be constructed with VRc::downgrade and use VWeak::upgrade
to re-create the original VRc.
Implementations
impl<VTable: VTableMetaDropInPlace + 'static, X> VWeak<VTable, X>[src]
pub fn upgrade(&self) -> Option<VRc<VTable, X>>[src]
Returns a new VRc if some other instance still holds a strong reference to this item.
Otherwise, returns None.
impl<VTable: VTableMetaDropInPlace + 'static, X: HasStaticVTable<VTable> + 'static> VWeak<VTable, X>[src]
pub fn into_dyn(self) -> VWeak<VTable, Dyn>[src]
Convert a VRc of a real instance to a VRc of a Dyn instance
