fake-stream

This is a fake stream for testing.

It writes and reads from the same buffer.

Example

```rust extern crate fake_stream;

use fake_stream::FakeStream;

fn main() { let mut fake = FakeStream::new();

let wl = fake.write(b"something").unwrap();

assert_eq!(9, wl);

let mut buf = [0; 5];

let rl = fake.read(&mut buf).unwrap();

assert_eq!(5, rl);

assert_eq!(buf, *b"somet");

let mut buf = *b"       ";

let rl = fake.read(&mut buf).unwrap();

assert_eq!(4, rl);

assert_eq!(buf, *b"hing   ");

} ```

tokio-codec Example

```rust fn main() { let mut fake = FakeStream::new(); let res = b"\ HTTP/1.1 200 OK\r\n\ Date: Mon, 27 Jul 2009 12:28:53 GMT\r\n\ Server: Apache/2.2.14 (Win32)\r\n\ Last-Modified: Wed, 22 Jul 2009 19:15:56 GMT\r\n\ Content-Length: 9\r\n\ Content-Type: text/html\r\n\r\n\ something"; let wl = fake.write(res).unwrap();

assert_eq!(res.len(), wl);

let mut framed = HttpCodec::new().framed(fake);

let response = match framed.poll().unwrap() {
    Async::Ready(Some(response)) => response,
    _ => panic!("no response"),
};

assert_eq!(response.status().as_u16(), 200);
assert_eq!(response.headers().len(), 5);
assert_eq!(response.body(), &Bytes::from_static(b"something"));

} ```
