Expand description
The scope accessors: the read and write entry points of a world.
A scope names the entity it is rooted at. It sees that entity, everything below it, and the shared subtree; it does not see its ancestors or its siblings. There is no way up: a scope cannot name the world it came from, so holding one is not a way to reach the rest.
Reading and writing components needs only Scope. Structural
changes – spawning, despawning, relinking – need ScopeMut, whose
operations are confined to the scope’s own subtree.
