rust - Hyper 0.11 でタイプ「hyper::Client」の「post」という名前のメソッドが見つかりません

Question

HTTP リクエストを作成するために Hyper を使用したい。呼び出しは正常に機能しますが、 andClient::getなどの他のメソッドはコンパイル エラーを引き起こします。Client::postClient::head

extern crate futures;
extern crate hyper;
extern crate tokio_core;

use std::io::{self, Write};
use futures::{Future, Stream};
use hyper::Client;
use tokio_core::reactor::Core;

fn main() {
    let mut core = Core::new().unwrap();
    let client = Client::new(&core.handle());

    let uri = "http://httpbin.org/ip".parse().unwrap();
    let work = client.post(uri).and_then(|res| {
        // if post changed to get it will work correctly
        println!("Response: {}", res.status());

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