Trait Element 

pub trait Element: Debug {
    type Label: Eq + Copy + Hash + Debug + Label + 'static;

    // Required method
    fn label(&self) -> Self::Label;

    // Provided method
    fn value(&self, _index: &<Self::Label as Label>::Index) -> Option<Value<'_>> { ... }
}

An element in a graph. This is either an edge or a vertex.
