# Struct hashbrown::hash_map::RawVacantEntryMut [−] [src]

    pub struct RawVacantEntryMut<'a, K, V, S> { /* fields omitted */ }

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

## Implementations

### `impl<'a, K, V, S> RawVacantEntryMut<'a, K, V, S>` [src]

#### `pub fn insert(self, key: K, value: V) -> (&'a mut K, &'a mut V) where
K: Hash,
S: BuildHasher,` [src]

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

#### `pub fn insert_hashed_nocheck(
self,
hash: u64,
key: K,
value: V
) -> (&'a mut K, &'a mut V) where
K: Hash,
S: BuildHasher,` [src]

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

#### `pub fn insert_with_hasher<H>(
self,
hash: u64,
key: K,
value: V,
hasher: H
) -> (&'a mut K, &'a mut V) where
H: Fn(&K) -> u64,` [src]

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