#[repr(u8)]
pub enum ArchivedRcWeak<T: ArchivePointee + ?Sized, F> {
    None,
    Some(ArchivedRc<T, F>),
}

Expand description

An archived rc::Weak.

This is essentially just an optional ArchivedRc.

Variants

`None`

A null weak pointer

`Some(ArchivedRc<T, F>)`

A weak pointer to some shared pointer

Implementations

source

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

source

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.

source

pub fn upgrade_pin_mut(
self: Pin<&mut Self>
) -> Option<Pin<&mut ArchivedRc<T, F>>>

Attempts to upgrade a pinned mutable weak pointer.

source

pub unsafe fn resolve_from_ref<U: ArchiveUnsized<Archived = T> + ?Sized>(
 value: Option<&U>,
 pos: usize,
 resolver: RcWeakResolver<MetadataResolver>,
 out: *mut Self
)

Resolves an archived Weak from a given optional reference.

Safety

pos must be the position of out within the archive
resolver must be the result of serializing value

source

pub fn serialize_from_ref<U, S>(
 value: Option<&U>,
 serializer: &mut S
) -> Result<RcWeakResolver<MetadataResolver>, S::Error> where
 U: SerializeUnsized<S, Archived = T> + ?Sized,
 S: Serializer + SharedSerializeRegistry + ?Sized,

Serializes an archived Weak from a given optional reference.
