Version support

Usage

serde_indextree provides two struct: Node for serializing a node and its descendants, SiblingNodes for serializing a node and its siblings in sequence.

use indextree::Arena;
use serde::Serialize;
use serde_indextree::Node;
use serde_json::to_string_pretty;

#[derive(Serialize)]
struct HtmlElement {
    tag: &'static str
}

// <html>
// <head>
//     <title></title>
// <head>
// <body>
//     <h1></h1>
//     <h2></h2>
// </body>
// </html>
let arena = &mut Arena::new();
let a = arena.new_node(HtmlElement { tag: "html" });
let b = arena.new_node(HtmlElement { tag: "head" });
a.append(b, arena);
let c = arena.new_node(HtmlElement { tag: "title" });
b.append(c, arena);
let d = arena.new_node(HtmlElement { tag: "body" });
a.append(d, arena);
let e = arena.new_node(HtmlElement { tag: "h1" });
d.append(e, arena);
let f = arena.new_node(HtmlElement { tag: "h2" });
d.append(f, arena);

println!("{}", to_string_pretty(&Node::new(a, arena)).unwrap());
// {
//   "tag": "html",
//   "children": [
//     {
//       "tag": "head",
//       "children": [
//         {
//           "tag": "title"
//         }
//       ]
//     },
//     {
//       "tag": "body",
//       "children": [
//         {
//           "tag": "h1"
//         },
//         {
//           "tag": "h2"
//         }
//       ]
//     }
//   ]
// }

Customization

Unfortunately, serde_indextree doesn't come up with any customization.

If you want to rename field names or anything, just copy the entire code (only 40+ lines) and modify it at your wish.
