Struct indexmap::map::VacantEntry [−][src]
A view into a vacant entry in a IndexMap.
It is part of the Entry enum.
Implementations
impl<'a, K, V> VacantEntry<'a, K, V>[src]
pub fn key(&self) -> &K[src]
Gets a reference to the key that was used to find the entry.
pub fn into_key(self) -> K[src]
Takes ownership of the key, leaving the entry vacant.
pub fn index(&self) -> usize[src]
Return the index where the key-value pair will be inserted.
pub fn insert(self, value: V) -> &'a mut V[src]
Inserts the entry’s key and the given value into the map, and returns a mutable reference to the value.
