## Picoquic-rs - Tokio aware bindings of [picoquic](https://github.com/private-octopus/picoquic)
[![](https://docs.rs/picoquic/badge.svg)](https://docs.rs/picoquic/) [![](https://img.shields.io/crates/v/picoquic.svg)](https://crates.io/crates/picoquic) [![](https://img.shields.io/crates/d/picoquic.png)](https://crates.io/crates/picoquic) [![Build Status](https://travis-ci.org/bkchr/picoquic-rs.png?branch=master)](https://travis-ci.org/bkchr/picoquic-rs)

Picoquic is a minimalist implementation of the QUIC protocol by the IETF. The protocol is still
in [development](https://github.com/quicwg) and so the implementation.

* [Contribution](#contribution)

### Building

For building picoquic-rs, you need the following dependencies:
* clang
* openssl
* cmake

Building is currently only tested on Linux. To build the project, you just need to
run `cargo build`.
`picoquic-sys` will also build the `picoquic` c-library for you (hopefully).

### Example

#### Client
```rust
extern crate bytes;
extern crate futures;
extern crate picoquic;
extern crate tokio_core;

use picoquic::{Config, Context, SMessage};

use tokio_core::reactor::Core;

use bytes::Bytes;

use futures::{Future, Sink, Stream};

fn main() {
    let mut evt_loop = Core::new().unwrap();

    let config = Config::client();

    let mut client = Context::new(&([0, 0, 0, 0], 0).into(), &evt_loop.handle(), config).unwrap();

    let mut con = evt_loop
        .run(client.new_connection(([127, 0, 0, 1], 22222).into()))
        .unwrap();

    let stream = evt_loop.run(con.new_bidirectional_stream()).unwrap();

    let stream = evt_loop
        .run(stream.send(SMessage::Data(Bytes::from("hello server"))))
        .unwrap();

    let answer = evt_loop
        .run(
            stream
                .into_future()
                .map(|(m, _)| m.unwrap())
                .map_err(|(e, _)| e),
        )
        .unwrap();

    println!("Got: {:?}", answer);
}
```

#### Server
```rust
extern crate bytes;
extern crate futures;
extern crate picoquic;
extern crate tokio_core;

use picoquic::{CMessage, Config, Context, SMessage};

use tokio_core::reactor::Core;

use futures::{Future, Sink, Stream};

use bytes::Bytes;

fn main() {
    let mut evt_loop = Core::new().unwrap();

    let manifest_dir = env!("CARGO_MANIFEST_DIR");

    let config = Config::server(
        &format!("{}/examples/cert.pem", manifest_dir),
        &format!("{}/examples/key.pem", manifest_dir),
    );

    let server = Context::new(&([0, 0, 0, 0], 22222).into(), &evt_loop.handle(), config).unwrap();

    println!("Server listening on: {}", server.local_addr());

    let handle = evt_loop.handle();

    evt_loop
        .run(server.for_each(|c| {
            println!("New connection from: {}", c.peer_addr());

            let handle = handle.clone();
            handle.clone().spawn(c.for_each(move |s| {
                // Let's see what we got
                let s = match s {
                    CMessage::NewStream(s) => s,
                    _ => return Ok(()),
                };

                // We print the received message and sent a new one, after that we collect all
                // remaining messages. The collect is a "hack" that prevents that the `Stream` is
                // dropped to early.
                handle.spawn(
                    s.into_future()
                        .map_err(|_| ())
                        .and_then(|(m, s)| {
                            println!("Got: {:?}", m);
                            s.send(SMessage::Data(Bytes::from("hello client")))
                                .map_err(|_| ())
                        })
                        .and_then(|s| s.collect().map_err(|_| ()))
                        .map(|_| ()),
                );
                Ok(())
            }).map_err(|_| ()));

            Ok(())
        }))
        .unwrap();
}
```

### Todo

* My first crate/project that uses `failure` and I'm not happy with the current error structure :(
* Support more configuration options
* I currently don't check all return codes of the c functions.
* Remove the TODOs from the source code
