Struct sentry_types::protocol::v7::map::OccupiedEntry

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

A view into a single occupied location in a LinkedHashMap.

Methods

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

impl<'a, R> Read for &'a mut R where
    R: Read + ?Sized, impl<'a, W> Write for &'a mut W where
    W: Write + ?Sized, impl<'a, I> Iterator for &'a mut I where

pub fn key(&self) -> &K

Gets a reference to the entry key

Examples

use linked_hash_map::LinkedHashMap;

let mut map = LinkedHashMap::new();

map.insert("foo".to_string(), 1);
assert_eq!("foo", map.entry("foo".to_string()).key());

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

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

Sets the value of the entry, and returns the entry's old value

pub fn remove(self) -> V

Takes the value out of the entry, and returns it
