Enum rkyv::std_impl::shared::ArchivedRcWeak [−][src]
#[repr(u8)] pub enum ArchivedRcWeak<T: ArchivePointee + ?Sized> { None, Some(ArchivedRc<T>), }
An archived rc::Weak.
Variants
A null weak pointer
Some(ArchivedRc<T>)A weak pointer to some shared pointer
Implementations
impl<T: ArchivePointee + ?Sized> ArchivedRcWeak<T>[src]
impl<T: ArchivePointee + ?Sized> ArchivedRcWeak<T>[src]pub fn upgrade(&self) -> Option<&ArchivedRc<T>>[src]
Attempts to upgrade the weak pointer to an ArchivedArc.
Returns None if a null weak pointer was serialized.
pub fn upgrade_pin(self: Pin<&mut Self>) -> Option<Pin<&mut ArchivedRc<T>>>[src]
Attempts to upgrade a pinned mutable weak pointer.
