Struct SelectThreeMany 

Source 
pub struct SelectThreeMany<E, F, G, TOP>
where
    E: EntityTrait,
    F: EntityTrait,
    G: EntityTrait,
    TOP: Topology,
{ /* private fields */ }
Expand description

Like SelectThree, but results are consolidated under the left model: (E::Model, Vec<F::Model>, Vec<G::Model>).
