Enum GroundProvider 

pub enum GroundProvider {
    Decorator,
    Mod(Arc<dyn GroundStateProvider>),
}

The provider a tree decorator places its ground with: AlterGroundEvent.getStateProvider.

Variants

Decorator

The decorator’s own (AlterGroundDecorator.provider).

Mod(Arc<dyn GroundStateProvider>)

A mod’s, in place of the one before. To change the ground only where it likes, a mod wraps the provider it found and asks it for the rest.
