Struct indexmap::map::VacantEntry[][src]

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

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.
