Struct rkyv_dyn::ArchivedDynMetadata
source · [−]pub struct ArchivedDynMetadata<T: ?Sized> { /* private fields */ }Expand description
The archived version of DynMetadata.
Implementations
sourceimpl<T: TypeName + ?Sized> ArchivedDynMetadata<T>
impl<T: TypeName + ?Sized> ArchivedDynMetadata<T>
sourcepub unsafe fn emplace(type_id: u64, out: *mut Self)
pub unsafe fn emplace(type_id: u64, out: *mut Self)
Creates a new ArchivedDynMetadata for the given type.
Safety
out must point to a valid location for an ArchivedDynMetadata<T>.
sourcepub fn vtable(&self) -> usize
pub fn vtable(&self) -> usize
Gets the vtable address for this trait object. With the vtable_cache feature, this will
store the address locally on the first lookup.
sourcepub fn pointer_metadata(&self) -> DynMetadata<T>
pub fn pointer_metadata(&self) -> DynMetadata<T>
Gets the DynMetadata associated with this ArchivedDynMetadata.

impl<T: TypeName + ?Sized, C: ?Sized> CheckBytes<C> for ArchivedDynMetadata<T>
type Error = DynMetadataError
type Error = DynMetadataError
The error that may result from checking the type.

unsafe fn check_bytes<'a>(
value: *const Self,
context: &mut C
