Implementations

impl<'a, K: IntegerId + 'a, V: 'a, T: EntryTable<K, V>> Entry<'a, K, V, T>

pub fn or_insert(self, value: V) -> &'a mut V

Return a reference to this entry’s value, initializing it with the specified value if its missing

pub fn or_insert_with<F>(self, func: F) -> &'a mut V where
    F: FnOnce() -> V, 

Return a reference to this entry’s value, using the closure to initialize it if its missing
