Struct Everything

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

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.
