Rust Wrapper for nanomsg-next-generation (nng)

This crate provides a safe wrapper around the nng library, seeking to maintain an API that is similar to the original library. Most features are complete and the library is usable in its current state.

The nng library is compiled and linked by default. If this is not the desired functionality (i.e., linking to the system installed nng is preferred), it can be disabled by setting default-features to false.

Example

```rust use nng::{Message, Protocol, Socket};

fn client() -> Result<(), nng::Error> { let mut s = Socket::new(Protocol::Req0)?; s.dial("tcp://127.0.0.1")?;

// Send the request to the response server
let mut req = Message::from(&[0xDE, 0xAD, 0xBE, 0xEF])?;
s.send(req)?;

// Wait for the response
let res = s.recv()?;
println!("Response: {:?}", res);

Ok(())

}

fn server() -> Result<(), nng::Error> { let mut s = Socket::new(Protocol::Rep0)?; s.listen("tcp://127.0.0.1")?;

loop {
    // Wait for a request from the client
    let mut msg = s.recv()?;

    // Respond to the client
    msg[1] += 1;
    s.send(msg)?;
}

} ```
