pub fn walk_nodes<'w, 'a>(
stmts: &'w [Stmt<'a>],
visit: impl FnMut(Visited<'w, 'a>) -> Walk,
)Expand description
for_each_node, with the visitor answering for each statement and expression whether the walk
goes on into its children. Exhaustive in the same way: a child is left unvisited only because a
visitor said so, never because the walk does not know the kind of node it is in.
