Module archetype 

Archetype storage.

An archetype owns all entities that have exactly the same set of component types, and stores one column per type. Rows of the different columns line up with Archetype::entities, so an entity’s archetype and row are enough to find every component it has.

Archetypes are created on demand and never removed; an empty archetype costs one allocation.
