Expand description

A registry that tracks deserialized shared memory.

This trait is required to deserialize shared pointers.

Required methods

Gets the data pointer of a previously-deserialized shared pointer.

Adds the data address of a deserialized shared pointer to the registry.

Provided methods

Checks whether the given reference has been deserialized and either uses the existing shared pointer to it, or deserializes it and converts it to a shared pointer with to_shared.
