pub struct VacantEntry<'a, K: 'a, V: 'a, S: 'a = RandomState> { /* fields omitted */ }

A view into a single empty location in a LinkedHashMap.

Methods

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

pub fn key(&self) -> &K

Gets a reference to the entry key

Examples

use linked_hash_map::LinkedHashMap;

let mut map = LinkedHashMap::<String, u32>::new();

assert_eq!("foo", map.entry("foo".to_string()).key());

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

Sets the value of the entry with the VacantEntry's key, and returns a mutable reference to it
