Struct EntitySystemSystemParamFunction 

Source 
pub struct EntitySystemSystemParamFunction<T: EntitySystem<In: Clone, Out = ()>>(pub T);
Expand description

SystemParamFunction, every time it’s run, it iterates over all the entities in the world that T can run on and runs T for them. Input will be cloned for every run of T.
