JSON UpdateString

See more JSON Examples

Demonstrates the JSON object's UpdateString method.

Note: The UpdateString method was introduced in Chilkat v9.5.0.63

Rust

// This example requires Chilkat v9.5.0.63 or greater.

let json = chilkat::JsonObject::new();
json.set_emit_compact(false);

// The UpdateString method updates or adds a string member.
// It also auto-creates the objects and/or arrays that
// are missing.  For example:
let _ = json.update_string("test.abc[0].xyz", "Chicago Cubs");

// The JSON now contains:
println!("{}", json.emit().unwrap_or_default());

// {
//   "test": {
//     "abc": [
//       {
//         "xyz": "Chicago Cubs"
//       }
//     ]
//   }

let _ = json.update_string("test.abc[0].xyz", "Chicago Cubs are going to win the World Series!");
println!("{}", json.emit().unwrap_or_default());

// {
//   "test": {
//     "abc": [
//       {
//         "xyz": "Chicago Cubs are going to win the World Series!"
//       }
//     ]
//   }
