Trait CollectionSource 

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

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<'b>( &'b self, no_gc: &'b NoGC, root: &'b Node, ) -> Box<dyn Iterator<Item = UnrootedDom<'b, Element>> + 'b>

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
