Trait rkyv::ArchiveCopy [−][src]
An Archive type that is a bitwise copy of itself and without additional processing.
Types that implement ArchiveCopy are not guaranteed to have a Serialize implementation
called on them to archive their value.
You can derive an implementation of ArchiveCopy by adding #[archive(copy)] to the struct or
enum. Types that implement ArchiveCopy must also implement Copy.
ArchiveCopy must be manually implemented even if a type implements Archive and
Copy because some types may transform their data when writing to an
archive.
Examples
use rkyv::{ archived_root, ser::{Serializer, serializers::WriteSerializer}, AlignedVec, Archive, Serialize, }; #[derive(Archive, Serialize, Clone, Copy, Debug, PartialEq)] #[archive(copy)] struct Vector4<T>(T, T, T, T); let mut serializer = WriteSerializer::new(AlignedVec::new()); let value = Vector4(1f32, 2f32, 3f32, 4f32); serializer.serialize_value(&value).expect("failed to archive Vector4"); let buf = serializer.into_inner(); let archived_value = unsafe { archived_root::<Vector4<f32>>(buf.as_ref()) }; assert_eq!(&value, archived_value);
