Struct Set 

pub struct Set<T>(pub(crate) GcCow<HashSet<T>>)
where
    T: Obj;

Garbage-collected hash set implementing Copy. This implements Ord but the order is not meaningful; this is just so one can use BTreeMaps. In particular, the order might differ across two runs of the same program.

Tuple Fields

0: GcCow<HashSet<T>>

Implementations

impl<T> Set<T>

where T: Obj,

pub fn new() -> Set<T>

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> Set<T>

where T: Obj,

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

An iterator over all elements of self.
