Struct WeakScope 

pub struct WeakScope(/* private fields */);

A WeakScope is a interior-mutable RwLock holding a map of weak shape references that can be used to resolve the Names of ShapeCase::Name shapes. Though this struct is pub, its [Ref<RwLock<WeakShapeMap>>] parameter is not, so you cannot directly create your own WeakScope outside this crate.
