Struct folda::PersistentRef

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

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.

Methods

impl<Key, Value> PersistentRef<Key, Value> where
    Key: Copy + Eq + Hash + 'static,
