Trait EntitySetIterator

pub unsafe trait EntitySetIterator: Iterator<Item: EntityEquivalent> {
    // Provided method
    fn collect_set<B: FromEntitySetIterator<Self::Item>>(self) -> B
       where Self: Sized { ... }
}

An iterator over a set of unique entities.

Every EntitySetIterator is also EntitySet.

Safety

x != y must hold for any 2 elements returned by the iterator. This is always true for iterators that cannot return more than one element.

Provided Methods

fn collect_set<B: FromEntitySetIterator<Self::Item>>(self) -> B

where Self: Sized,

Transforms an EntitySetIterator into a collection.

This is a specialized form of collect, for collections which benefit from the uniqueness guarantee. When present, this should always be preferred over collect.
