Example on crates.io does not compile about warp

[seanmonstar]

Yea, it was written with the new Rust 2018 macro syntax. It's currently fixed on master.

[seanmonstar]

With the publish of 0.1.1, the shown example should now be correct.

The example code does not seem to work anymore, on Rust 1.39.0

Code (retrieved from https://crates.io/crates/warp)

// src/main.rs
use warp::{self, path, Filter};

fn main() {
    // GET /hello/warp => 200 OK with body "Hello, warp!"
    let hello = path!("hello" / String)
        .map(|name| format!("Hello, {}!", name));

    warp::serve(hello)
        .run(([127, 0, 0, 1], 3030));
}

Error(s)

Hi, yeah crates.io uses the repo README.md as the frontpage for the crate, and the example was only updated on #384 after the release of 0.2.0, you can use the README.md example

The crates.io example should probably include tokio dependencies too.
