Expand description
Syntax tree traversal to mutate an exclusive borrow of a syntax tree in place.
Each method of the VisitMut trait is a hook that can be overridden
to customize the behavior when mutating the corresponding type of node.
By default, every method recursively visits the substructure of the
input by invoking the right visitor method of each of its fields.
pub trait VisitMut {
/* ... */
fn visit_expr_binary_mut(&mut self, node: &mut ExprBinary) {
for attr in &mut node.attrs {
self.visit_attribute_mut(attr);
}
self.visit_expr_mut(&mut *node.left);
self.visit_bin_op_mut(&mut node.op);
self.visit_expr_mut(&mut *node.right);
}
/* ... */
}This module is available if Syn is built with the "visit-mut"
feature.
