pub struct RawVacantEntryMut<'map, K, V, S>(_);

Expand description

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

Implementations

source

impl<'map, K, V, S> RawVacantEntryMut<'map, K, V, S> where
S: BuildHasher,

source

pub fn insert(self, key: K, value: V) -> (&'map mut K, &'map mut V) where
K: Hash,
S: BuildHasher,

Sets the value of the entry with the VacantEntry’s key, and returns a mutable reference to it.

source

pub fn insert_hashed_nocheck(
    self,
    hash: u64,
    key: K,
    value: V
) -> (&'map mut K, &'map mut V) where
    K: Hash,
    S: BuildHasher,

Sets the value of the entry with the VacantEntry’s key, and returns a mutable reference to it.

source

pub fn insert_with_hasher<H>(
 self,
 hash: u64,
 key: K,
 value: V,
 hasher: H
) -> (&'map mut K, &'map mut V) where
 S: BuildHasher,
 H: Fn(&K) -> u64,

Set the value of an entry with a custom hasher function.
