Struct ArchivedRc

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

Available on crate feature dep_rkyv only.

An archived Rc.

This is a thin wrapper around a RelPtr to the archived type paired with a “flavor” type. Because there may be many varieties of shared pointers and they may not be used together, the flavor helps check that memory is not being shared incorrectly during validation.

Implementations

impl<T, F> ArchivedRc<T, F>

where T: ArchivePointee + ?Sized,

pub fn get(&self) -> &T

Gets the value of the ArchivedRc.

pub unsafe fn get_seal_unchecked( this: Seal<'_, ArchivedRc<T, F>>, ) -> Seal<'_, T>

Gets the sealed value of this ArchivedRc.

Safety

Any other pointers to the same value must not be dereferenced for the duration of the returned borrow.

pub fn resolve_from_ref<U>( value: &U, resolver: RcResolver, out: Place<ArchivedRc<T, F>>, )

where U: ArchiveUnsized<Archived = T> + ?Sized,

Resolves an archived Rc from a given reference.

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