Methods

impl<'a, K: 'a, V: 'a, S: 'a> Entry<'a, K, V, S> where
    K: Eq + Hash,
    S: BuildHasher, 

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

Returns a mutable reference to a value if the entry exists, or creates a new entry using a given closure if it doesn't exist yet and returns a reference to a newly created entry's value.

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

Returns a mutable reference to a value if the entry exists, or creates a new entry with a given value if it doesn't exist yet and returns a reference to a newly created entry's value.
