Trait DeserializeUnsized

pub trait DeserializeUnsized<T: Pointee + ?Sized, D: Fallible + ?Sized>: ArchivePointee {
    // Required methods
    unsafe fn deserialize_unsized(
        &self,
        deserializer: &mut D,
        alloc: impl FnMut(Layout) -> *mut u8,
    ) -> 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.

Required Methods

unsafe fn deserialize_unsized( &self, deserializer: &mut D, alloc: impl FnMut(Layout) -> *mut u8, ) -> Result<*mut (), D::Error>

Deserializes a reference to the given value.

Safety

out must point to memory with the layout returned by deserialized_layout.

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

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.
