Trait ArchetypeQueryData 

pub trait ArchetypeQueryData: QueryData { }

A marker trait to indicate that the query data filters at an archetype level.

This is needed to implement ExactSizeIterator for QueryIter that contains archetype-level filters.

The trait must only be implemented for query data where its corresponding QueryData::IS_ARCHETYPAL is true.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
