Module hash_map

A hash map implemented with quadratic probing and SIMD lookup.

Structs

Drain

A draining iterator over the entries of a HashMap in arbitrary order. The iterator element type is (K, V).

ExtractIf

A draining iterator over entries of a HashMap which don’t satisfy the predicate f(&k, &mut v) in arbitrary order. The iterator element type is (K, V).

HashMap

A hash map implemented with quadratic probing and SIMD lookup.

IntoIter

An owning iterator over the entries of a HashMap in arbitrary order. The iterator element type is (K, V).

IntoKeys

An owning iterator over the keys of a HashMap in arbitrary order. The iterator element type is K.

IntoValues

An owning iterator over the values of a HashMap in arbitrary order. The iterator element type is V.

Iter

An iterator over the entries of a HashMap in arbitrary order. The iterator element type is (&'a K, &'a V).

IterMut

A mutable iterator over the entries of a HashMap in arbitrary order. The iterator element type is (&'a K, &'a mut V).

Keys

An iterator over the keys of a HashMap in arbitrary order. The iterator element type is &'a K.

OccupiedEntry

A view into an occupied entry in a HashMap. It is part of the Entry and EntryRef enums.

OccupiedError

The error returned by try_insert when the key already exists.

RawEntryBuilder

A builder for computing where in a HashMap a key-value pair would be stored.

RawEntryBuilderMut

A builder for computing where in a HashMap a key-value pair would be stored.

RawOccupiedEntryMut

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

RawVacantEntryMut

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

VacantEntry

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

VacantEntryRef

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

Values

An iterator over the values of a HashMap in arbitrary order. The iterator element type is &'a V.

ValuesMut

A mutable iterator over the values of a HashMap in arbitrary order. The iterator element type is &'a mut V.

Enums

Entry

A view into a single entry in a map, which may either be vacant or occupied.

EntryRef

A view into a single entry in a map, which may either be vacant or occupied, with any borrowed form of the map’s key type.

RawEntryMut

A view into a single entry in a map, which may either be vacant or occupied.
