Struct in_place::dummy_collections::hash_map::DummyHashMapOccupiedEntry

pub struct DummyHashMapOccupiedEntry<'c, K, V> { /* private fields */ }

Occupied entry of a HashMap.

This entry can be used to read the key, mutate the value, or remove the key/value pair from the HashMap, without re-hashing.

Trait Implementations

impl<'c, K, V> EntryRemovableOccupiedEntry<'c> for DummyHashMapOccupiedEntry<'c, K, V>

type Vacant = DummyHashMapVacantEntry<'c, K, V>

fn recover_removed_entry(removed: Self::Removed) -> DummyHashMapEntry<'c, K, V>

impl<'c, K, V> KeyedOccupiedEntry<'c> for DummyHashMapOccupiedEntry<'c, K, V>

type Key = K

the type of the keys in the collection

type BorrowedKey = &'c K

fn get_pair<'e>(&'e self) -> (&'e Self::Key, &'e Self::Value) where
    'c: 'e, 

get the key value pair, immutably borrowed

fn get_pair_mut<'e>(&'e mut self) -> (&'e Self::Key, &'e mut Self::Value) where
    'c: 'e, 

get the key value pair. the key is immutably borrowed, and the value immutably.

fn into_pair(self) -> (Self::BorrowedKey, &'c mut Self::Value)

convert the entry into key value pair. the key is immutably borrowed, and the value immutably.

impl<'c, K, V> OccupiedEntry<'c> for DummyHashMapOccupiedEntry<'c, K, V>

type Value = V

the type of the values in the collection

fn get_value<'e>(&'e self) -> &'e Self::Value where
    'c: 'e, 

get the value, immutably borrowed.

fn get_value_mut<'e>(&'e mut self) -> &mut Self::Value where
    'c: 'e, 

get the value, mutably borrowed.

fn into_value_mut<'e>(self) -> &'c mut Self::Value

convert the entry into a mutable to the value.

fn replace_value<'e>(&'e mut self, value: Self::Value) -> Self::Value where
    'c: 'e, 

replace the value in the entry, returning the old value.

impl<'c, K, V> RemovableOccupiedEntry<'c> for DummyHashMapOccupiedEntry<'c, K, V>

type Removed = DummyHashMapVacantEntry<'c, K, V>

The type returned when removing the OccupiedEntry

fn remove(self) -> (V, Self::Removed)

remove this entry from the collection, converting the entry into a Self::Removed and returning the value that was there.

fn remove_value(self) -> Self::Value

remove this entry from the collection, consuming the entry and returning the value that was there.

fn vacate(self) -> (Self::Value, Self::Removed) where
    Self::Removed: VacantEntry<'c, Occupied = Self>, 

remove this entry, returning a value and a vacant entry.
