Struct Set 

pub struct Set<T: Obj>(/* private fields */);

Garbage-collected hash set implementing Copy.

Implementations

impl<T: Obj> Set<T>

pub fn new() -> Self

Constructs an empty Set.

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

Checks whether t is contained in self.

pub fn insert(&mut self, t: T)

Inserts t into self.

pub fn try_insert(&mut self, t: T) -> Result<(), ()>

Like insert, but fails if t was already in the set.

pub fn remove(&mut self, t: T)

Removes t from self.

pub fn len(self) -> Int

Returns the number of elements in self.

pub fn is_empty(self) -> bool

Returns true if the set contains no elements.

impl<T: Obj> Set<T>

pub fn iter(self) -> ConsumingIter<T>

An iterator over all elements of self.

Trait Implementations

impl<T: Clone + Obj> 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 + Obj> Debug for Set<T>

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

Formats the value using the given formatter.

impl<T: Obj> Default for Set<T>

fn default() -> Self

Returns the “default value” for a type.

impl<U: Obj> FromIterator<U> for Set<U>

fn from_iter<T>(iter: T) -> Self

where T: IntoIterator<Item = U>,

Creates a value from an iterator.

impl<T: Hash + Obj> Hash for Set<T>

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<T: Obj> IntoIterator for Set<T>

type Item = T

The type of the elements being iterated over.

type IntoIter = ConsumingIter<T>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl<T: PartialEq + Obj> PartialEq for Set<T>

fn eq(&self, other: &Set<T>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
