Struct PersistentRef

pub struct PersistentRef<Key, Value>
where
    Key: Copy + Eq + Hash + 'static,
    Value: 'static,
{ /* private fields */ }

A warpper represents managed data. This struct gives shared, readonly access to the value. When user want to use some sort of data stored in the DB, it should always be warpped in this type. When the value is dropped, it’s stored to a persistent storage.
