Struct OccupiedEntry

source 
pub struct OccupiedEntry<'a, K, V>
where
    K: Ord,
{ /* private fields */ }
Expand description

A view into an occupied entry in a IndexMap.

It is part of the Entry enum.

Implementations§

source§

impl<'a, K, V> OccupiedEntry<'a, K, V>
where K: 'a + Ord + Clone, V: 'a,

source

pub fn key(&self) -> &K

Gets a reference to the key in the entry.

source

pub fn get(&self) -> &V

Gets a reference to the value in the entry.

source

pub fn get_mut(&mut self) -> &mut V

Gets a mutable reference to the value in the entry.

source

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

Sets the value of the entry with the OccupiedEntry’s key, and returns the entry’s old value.

source

pub fn into_mut(self) -> &'a mut V

Converts the OccupiedEntry into a mutable reference to the value in the entry with a lifetime bound to the map itself.
