Function channel 

pub fn channel<T>(
    name: &str,
    data_dir: &Path,
) -> Result<(Sender<T>, Receiver<T>), Error>
where
    T: Serialize + DeserializeOwned,

Create a (Sender, Reciever) pair in a like fashion to std::sync::mpsc::channel

This function creates a Sender and Receiver pair with name name whose queue files are stored in data_dir. The maximum number of bytes that will be stored in-memory is 1Mb and the maximum size of a queue file will be 100Mb. The Sender is clonable.

Example

extern crate tempdir;
extern crate hopper;

let dir = tempdir::TempDir::new("hopper").unwrap();
let (mut snd, mut rcv) = hopper::channel("example", dir.path()).unwrap();

snd.send(9);
assert_eq!(Some(9), rcv.iter().next());
