Struct rin::ecs::ReadNot

pub struct ReadNot<'a, T, Not> where
    Not: 'static,
    T: Component,
    <T as Component>::Storage: for<'s> Storage<'s, T>,  { /* fields omitted */ }

Operator that matches every entity that has the first component and not the second

It’s equivalent to Read + Not but more convenient cause it doesn’t return an extra empty component

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

Will select all entities that have Position but no Velocity
