Trait GcRoots 

pub trait GcRoots {
    // Required method
    fn trace_roots(&self, tracer: &mut dyn FnMut(ArenaIndex));
}

Trait for types that contain GC roots.

Implementors should call tracer for each ArenaIndex that represents a live GC root. This ensures the garbage collector does not collect reachable objects.

By centralizing root enumeration in this trait, adding a new ArenaIndex field to a type will produce a compile-time reminder (or at least a single, obvious place) to update root tracking, rather than requiring updates in every GC call-site.

Required Methods

fn trace_roots(&self, tracer: &mut dyn FnMut(ArenaIndex))

Call tracer once for every ArenaIndex that is a live GC root.
