Module fold 

Owned AST transformation via the FoldOwned trait.

FoldOwned is the transformation counterpart of super::visitor::OwnedVisitor. Where OwnedVisitor reads nodes in place, FoldOwned rebuilds them — reading from an input node (borrowed) and returning a new owned value. Override only the node types you want to change; all others are rebuilt identically by the default implementations (equivalent to Clone).

Example

use php_ast::owned::fold::{FoldOwned, fold_owned_expr};
use php_ast::owned::{Expr, ExprKind};

struct NegateInts;

impl FoldOwned for NegateInts {
    fn fold_expr(&mut self, expr: &Expr) -> Expr {
        if let ExprKind::Int(n) = &expr.kind {
            return Expr { kind: ExprKind::Int(-n), span: expr.span };
        }
        fold_owned_expr(self, expr)
    }
}
