Struct PersistedRefMut

Source 
pub struct PersistedRefMut<'a, S, K>
where
    S: PersistedStore<K>,
    K: PersistedKey,
{ /* private fields */ }
Expand description

A guard encompassing the lifespan of a mutable reference to a persisted value. The purpose of this is to save the value immediately after it is mutated.
