Trait rkyv::DeserializeUnsized

pub trait DeserializeUnsized<T: ArchiveUnsized<Archived = Self> + ?Sized, D: Fallible + ?Sized>: ArchivePointee {
    unsafe fn deserialize_unsized(
        &self, 
        deserializer: &mut D
    ) -> Result<*mut (), D::Error>;
    fn deserialize_metadata(
        &self, 
        deserializer: &mut D
    ) -> Result<T::Metadata, D::Error>;
}

A counterpart of Deserialize that’s suitable for unsized types.

Most types that implement DeserializeUnsized will need a Deserializer bound so that they can allocate memory.

Required methods

unsafe fn deserialize_unsized(
    &self,
    deserializer: &mut D
) -> Result<*mut (), D::Error>

Deserializes a reference to the given value.

Safety

The caller must guarantee that the memory returned is properly deallocated.

fn deserialize_metadata(
    &self,
    deserializer: &mut D
) -> Result<T::Metadata, D::Error>

Deserializes the metadata for the given type.
