Struct scrapmetal::Everything

pub struct Everything<Q, R, F> where
    Q: GenericQuery<R>,
    F: FnMut(R, R) -> R,  { /* fields omitted */ }

Recursively perform a query in a top-down, left-to-right manner across a data structure. The Q: Query<R> queries individual values, while the F: FnMut(R, R) -> R joins the results of multiple queries into a single result.
