tokio-fs = "0.1"
```

```rust
// src/main.rs

extern crate file_futures;
extern crate futures;
extern crate tokio_fs;
```

### Example
```rust
use std::io::SeekFrom;

use file_futures::AsyncFile;
use futures::Future;
use tokio_fs::File;

fn main() {
    let future = File::create("/tmp/some-tmpfile")
        .map_err(|e| println!("Create Error {}", e))
        .and_then(|_| {
            let future1 = File::open("/tmp/some-tmpfile")
                .and_then(|file| file.metadata().and_then(|(_file, _metadata)| Ok(())))
                .map_err(|e| println!("Error1: {}", e));

            let future2 = File::open("/tmp/some-tmpfile")
                .and_then(|file| {
                    file.seek(SeekFrom::Start(30))
                        .and_then(|(_file, _from_start)| Ok(()))
                })
                .map_err(|e| println!("Error2: {}", e));

            future1.join(future2)
        });

    tokio::run(future.map(|_| ()));
}
```
