pub fn map_children(
expr: SqlExpression,
f: impl FnMut(SqlExpression) -> SqlExpression,
) -> SqlExpressionExpand description
Rebuild expr, replacing each direct child expression with f(child).
Leaf nodes are returned unchanged. Subquery statements are a scope boundary
and are not descended into — see the module docs. Use
map_children_crossing when you need to rewrite them too.
