Function visit_children_crossing 

Source 
pub fn visit_children_crossing<'a, C>(
    expr: &'a SqlExpression,
    ctx: &mut C,
    f: impl FnMut(&mut C, &'a SqlExpression),
    f_stmt: impl FnMut(&mut C, &'a SelectStatement),
)
Expand description

Call f on each direct child expression of expr and f_stmt on each directly nested subquery statement.

The borrowing counterpart to map_children_crossing, and the primitive visit_children is built on. As there, the subquery-bearing variants are listed only here, so a new one is a compile error rather than a silent skip at every call site, and ctx carries the state the two closures share.
