Implementations

`impl<'a, K: Ord, V> VacantEntry<'a, K, V>`

fn key(self: &Self) -> &K: Gets a reference to the key that would be used when inserting a value through the VacantEntry.
fn insert(self: Self, value: V) -> &'a mut V: Sets the value of the entry with the VacantEntry's key, and returns a mutable reference to it.
