Struct Set 

pub struct Set<T> { /* private fields */ }

Implementations

impl<T: Clone + Hash + PartialEq> Set<T>

pub fn iter(&self) -> impl Iterator<Item = &T>

C++ begin()/end() over live entries only. erase leaves tombstones in the underlying map, so iteration must skip entries whose presence bit is false.

impl<T: Clone + Hash + PartialEq> Set<T>

pub fn clear(&mut self)

impl<T: Clone + Hash + PartialEq> Set<T>

pub fn contains(&self, element: &T) -> bool

impl<T: Clone + Hash + PartialEq> Set<T>

pub fn count(&self, element: &T) -> usize

C++ size_t count(const T& element) const.

impl<T: Clone + Hash + PartialEq> Set<T>

pub fn empty(&self) -> bool

impl<T: Clone + Hash + PartialEq> Set<T>

pub fn erase(&mut self, element: &T)

C++ void erase(T&& element) / void erase(const T& element) — tombstones the entry (sets it false) rather than removing the slot.

impl<T: Clone + Hash + PartialEq> Set<T>

pub fn insert(&mut self, element: &T) -> bool

C++ bool insert(const T& element) — true when newly inserted.

impl<T: Clone + Hash + PartialEq> Set<T>

pub fn insert_range<'a, I: Iterator<Item = &'a T>>(&mut self, items: I)

where T: 'a,

C++ template<class Iterator> void insert(Iterator begin, Iterator end).

impl<T: Clone + Hash + PartialEq> Set<T>

pub fn operator_eq(&self, there: &Set<T>) -> bool

C++ bool operator==(const Set<T>& there) const. NOTE: transcribed 1:1 INCLUDING the upstream bug — the condition reads present && there.contains(elem) where the comment says it means to check “if it’s NOT in there”. Faithful ports match reference behavior.

impl<T: Clone + Hash + PartialEq> Set<T>

pub fn new(empty_key: T) -> Self

C++ explicit Set(const T& empty_key).

impl<T: Clone + Hash + PartialEq> Set<T>

pub fn size(&self) -> usize

Trait Implementations

impl<T: Clone> Clone for Set<T>

fn clone(&self) -> Set<T>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<T: Debug> Debug for Set<T>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
