我正在尝试轮询GitHub API中的问题并打印出来。为此，我需要反序列化从cURL GET请求中收到的嵌套JSON结构。

我正在尝试获取数组中url所有对象的items：

 "incomplete_results": false,
 "items": [
    {
     "url": "https://api.github.com/repos/servo/saltfs/issues/789",

我有两个文件,loop.rs包含一个函数请求来实例化客户端并获取一个网页的主体.我想将请求导出到main.我知道要出口我需要mod file_to_import然后use file_to_import::function_to_use根据这篇文章

src/
   main.rs
   loop.rs


// loop.rs ->
//crates
extern crate futures;
extern crate hyper;
extern crate tokio_core;
use std::io::{self, Write};
use self::futures::{Future, Stream};
use self::hyper::Client;
use self::tokio_core::reactor::Core;


//request function to be exported to main.rs

pub fn request(url: &str)  {
   let mut core = Core::new().unwrap();
   let client = Client::new(&core.handle());
   let uri = url.parse().unwrap();
   let work = client.get(uri).and_then(|res| {
      println!("Response: {}", res.status());

      res.body().for_each(|chunk| {
         io::stdout()
         .write_all(&chunk)
         .map_err(From::from)
     })
});
core.run(work).unwrap();
}
