Trait CollectionSource 

pub(crate) trait CollectionSource: JSTraceable {
    // Required method
    fn iter<'a>(
        &'a self,
        root: &'a Node,
    ) -> Box<dyn Iterator<Item = DomRoot<Element>> + 'a>;
}

Alternative to CollectionFilter that provides elements directly via a custom iterator, rather than filtering a tree traversal. This is more efficient when the collection’s elements can be enumerated directly (e.g. selectedOptions iterating only the select’s list of options).

Required Methods

fn iter<'a>( &'a self, root: &'a Node, ) -> Box<dyn Iterator<Item = DomRoot<Element>> + 'a>
