reqwest::get查询 Github 的stargazers API v3，获取星号标记项目的所有用户的列表。reqwest::Response用Response::json反序列化为User对象，而这对象实现了serde::Deserialize。

#[macro_use]
extern crate serde_derive;
extern crate reqwest;
use reqwest::Error;

#[derive(Deserialize, Debug)]
struct User {
    login: String,
    id: u32,
}

fn main() -> Result<(), Error> {
    let request_url = format!("https://api.github.com/repos/{owner}/{repo}/stargazers",
                              owner = "rust-lang-nursery",
                              repo = "rust-cookbook");
    println!("{}", request_url);
    let mut response = reqwest::get(&request_url)?;

    let users: Vec<User> = response.json()?;
    println!("{:?}", users);
    Ok(())
}
