Methods

impl<'a, K: 'a, V: 'a> Entry<'a, K, V>

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

Ensures that the entry is occupied by inserting it into the map with the given value if it is vacant.

Returns a mutable reference to the value with the same lifetime as the map.

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

Ensures that the entry is occupied by inserting it into the map with the result of the given function if it is vacant.

Returns a mutable reference to the value with the same lifetime as the map.
