Expand description

Mutable visitor trait for the statement AST.

Implement this trait to walk and modify the AST in place. Each visit_*_mut method has a default implementation that recurses into child nodes via the corresponding free function (e.g., visit_expr_mut). Override specific methods to transform nodes of interest.

Companion helpers:

for_each_expr_mut – visits every expression node in post-order.
walk_expr_scoped_mut – walks expressions while tracking Let/Map scope depth.

§Examples

use toasty_core::stmt::{visit_mut, Expr, Value, Node};

let mut expr = Expr::from(Value::from(42_i64));
visit_mut::for_each_expr_mut(&mut expr, |e| {
    // transform expressions in place
});
