Struct std_shims::collections::hash_map::RawOccupiedEntryMut

pub struct RawOccupiedEntryMut<'a, K, V, S>
where
    K: 'a,
    V: 'a,
    S: 'a,
{ /* private fields */ }

🔬This is a nightly-only experimental API. (hash_raw_entry)

Available on crate feature std only.

A view into an occupied entry in a HashMap. It is part of the RawEntryMut enum.

Implementations

impl<'a, K, V, S> RawOccupiedEntryMut<'a, K, V, S>

pub fn key(&self) -> &K

🔬This is a nightly-only experimental API. (hash_raw_entry)

Gets a reference to the key in the entry.

pub fn key_mut(&mut self) -> &mut K

🔬This is a nightly-only experimental API. (hash_raw_entry)

Gets a mutable reference to the key in the entry.

pub fn into_key(self) -> &'a mut K

🔬This is a nightly-only experimental API. (hash_raw_entry)

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

pub fn get(&self) -> &V

🔬This is a nightly-only experimental API. (hash_raw_entry)

Gets a reference to the value in the entry.

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

🔬This is a nightly-only experimental API. (hash_raw_entry)

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

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

🔬This is a nightly-only experimental API. (hash_raw_entry)

Gets a mutable reference to the value in the entry.

pub fn get_key_value(&mut self) -> (&K, &V)

🔬This is a nightly-only experimental API. (hash_raw_entry)

Gets a reference to the key and value in the entry.

pub fn get_key_value_mut(&mut self) -> (&mut K, &mut V)

🔬This is a nightly-only experimental API. (hash_raw_entry)

Gets a mutable reference to the key and value in the entry.

pub fn into_key_value(self) -> (&'a mut K, &'a mut V)

🔬This is a nightly-only experimental API. (hash_raw_entry)

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

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

🔬This is a nightly-only experimental API. (hash_raw_entry)

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

pub fn insert_key(&mut self, key: K) -> K

🔬This is a nightly-only experimental API. (hash_raw_entry)

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

pub fn remove(self) -> V

🔬This is a nightly-only experimental API. (hash_raw_entry)

Takes the value out of the entry, and returns it.

pub fn remove_entry(self) -> (K, V)

🔬This is a nightly-only experimental API. (hash_raw_entry)

Take the ownership of the key and value from the map.
