Struct rin::ecs::Has

pub struct Has<T> { /* fields omitted */ }

Operator that matches every entity that doe has this component without locking it’s storage

The selected data will have a () element in it’s position.

for (pos, _) in entities.iter_for::<(Read<Position>, Has<Velocity>)>(){
    //...
}

Will select all entities that have Position and Velocity
