extern crate reqwest;

fn main() {
    let response = reqwest::get("https://www.example.com/data.json")
        .expect("Failed to send request");

    let json: serde_json::Value = response.json()
        .expect("Failed to parse JSON response");

    println!("{}", json);
}

{
  "name": "John Doe",
  "age": 42
}
