JSON: Renaming and Deleting Members

See more JSON Examples

Demonstrates renaming and deleting members. This example uses the following JSON document:

{
   "apple": "red",
   "lime": "green",
   "banana": "yellow",
   "broccoli": "green",
   "strawberry": "red"
}

Rust

let json = chilkat::JsonObject::new();

if json.load("{\"apple\": \"red\",\"lime\": \"green\",\"banana\": \"yellow\",\"broccoli\": \"green\",\"strawberry\": \"red\"}").is_err() {
    println!("{}", json.last_error_text());
    return;
}

// Rename "lime" to "lemon".
let _ = json.rename("lime", "lemon").is_ok();
// Change the color to yellow:
let _ = json.set_string_of("lemon", "yellow").is_ok();

// Rename by index.  Banana is at index 2 (apple is at index 0)
let _ = json.rename_at(2, "bartlett_pear").is_ok();

// Delete broccoli by name
let _ = json.delete("broccoli").is_ok();

// Delete apple by index.  Apple is at index 0.
let _ = json.delete_at(0).is_ok();

json.set_emit_compact(false);
println!("{}", json.emit().unwrap_or_default());
