Struct rin::ecs::operators::Read

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

Operator that matches all entities that contain this component for read only access

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

Will iterate over all position components
