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

A view into a vacant raw entry in an IndexMap. It is part of the RawEntryMut enum.

Implementations§

source§

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

source

pub fn index(&self) -> usize

Return the index where a key-value pair may be inserted.

source

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

Inserts the given key and value into the map, and returns mutable references to them.

source

pub fn insert_hashed_nocheck( self, hash: u64, key: K, value: V ) -> (&'a mut K, &'a mut V)

Inserts the given key and value into the map with the provided hash, and returns mutable references to them.

source

pub fn shift_insert( self, index: usize, key: K, value: V ) -> (&'a mut K, &'a mut V)
where K: Hash, S: BuildHasher,

Inserts the given key and value into the map at the given index, shifting others to the right, and returns mutable references to them.

Panics if index is out of bounds.

Computes in O(n) time (average).

source

pub fn shift_insert_hashed_nocheck( self, index: usize, hash: u64, key: K, value: V ) -> (&'a mut K, &'a mut V)

Inserts the given key and value into the map with the provided hash at the given index, and returns mutable references to them.

Panics if index is out of bounds.

Computes in O(n) time (average).
