Trait DeserializeUnsized

pub trait DeserializeUnsized<T, D>: ArchivePointee
where
    T: Pointee + ?Sized,
    D: Fallible + ?Sized,
{
    // Required methods
    unsafe fn deserialize_unsized(
        &self,
        deserializer: &mut D,
        out: *mut T,
    ) -> Result<(), <D as Fallible>::Error> ;
    fn deserialize_metadata(&self) -> <T as Pointee>::Metadata;
}

Available on crate feature dep_rkyv only.

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

Required Methods

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

Deserializes a reference to the given value.

Safety

out must be non-null, properly-aligned, and valid for writes. It must be allocated according to the layout of the deserialized metadata.

fn deserialize_metadata(&self) -> <T as Pointee>::Metadata

Deserializes the metadata for the given type.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
