Implementations

[src]

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

[src]

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

[src]

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

Call the specified closure to compute a value to insert, then proceed by calling VacantEntry::insert
