Struct rkyv::rc::ArchivedRcWeak

pub struct ArchivedRcWeak<T: ArchivePointee + ?Sized, F> { /* private fields */ }

An archived rc::Weak.

This is essentially just an optional ArchivedRc.

Implementations

impl<T: ArchivePointee + ?Sized, F> ArchivedRcWeak<T, F>

pub fn upgrade(&self) -> Option<&ArchivedRc<T, F>>

Attempts to upgrade the weak pointer to an ArchivedArc.

Returns None if a null weak pointer was serialized.

pub fn upgrade_seal(this: Seal<'_, Self>) -> Option<Seal<'_, ArchivedRc<T, F>>>

Attempts to upgrade a sealed weak pointer.

pub fn resolve_from_ref<U: ArchiveUnsized<Archived = T> + ?Sized>( value: Option<&U>, resolver: RcWeakResolver, out: Place<Self>, )

Resolves an archived Weak from a given optional reference.

pub fn serialize_from_ref<U, S>( value: Option<&U>, serializer: &mut S, ) -> Result<RcWeakResolver, S::Error>

where U: SerializeUnsized<S, Archived = T> + ?Sized, S: Fallible + Writer + Sharing + ?Sized, S::Error: Source,

Serializes an archived Weak from a given optional reference.
