Struct RawVacantEntryMut

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

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

Implementations

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

pub fn index(&self) -> usize

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

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.

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.

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).

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).

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
