Enum LoadedRelation 

pub enum LoadedRelation {
    Loaded,
    Empty,
    NotLoaded,
}

The explicit load state of a relation stored in the runtime identity graph.

Reading this state never performs I/O. NotLoaded means exactly that the current query did not install a value for the relation; callers must issue an explicit query if they need it.
