Struct RootedTraceableBox 

pub(crate) struct RootedTraceableBox<T>(RootedTraceableBox<T>)
where
    T: Traceable + 'static;

Roots any JSTraceable thing

If you have a valid DomObject, use DomRoot. If you have GC things like *mut JSObject or JSVal, use rooted!. If you have an arbitrary number of DomObjects to root, use rooted_vec!. If you know what you’re doing, use this.
