A cross-platform event loop library of asynchroneous network sockets.

This is a simple wrapper of network library, D language implementation. Its encapsulation is simple and clear, and is very suitable for reading and reference. Though very small, its performance is pretty good, It's a real full duplex mode.

Support platform:

• Platforms
• FreeBSD
• Windows
• OSX
• Linux
• NetBSD
• OpenBSD

Support for kernel loop (while supporting IN and OUT event listener):

• Epoll
• Kqueue
• IOCP

Quick Start:

// Echo server:

import async;
import std.stdio;
import std.socket;
import std.exception;

void main()
{
    auto listener = new TcpListener();
    listener.bind(new InternetAddress(12290));
    listener.listen(10);

    auto loop = new EventLoop(listener, null, null, &onReceive, null, null);
    loop.run();
}

void onReceive(TcpClient client, const scope ubyte[] data) nothrow @trusted
{
    collectException({
        writefln("Receive from %s: %d", client.remoteAddress, data.length);
        client.send(cast(ubyte[])data);
    }());
}


// Echo client:

import std.stdio;
import std.socket;

void main(string[] argv)
{
    auto socket = new TcpSocket();
    socket.connect(new InternetAddress("127.0.0.1", 12290));

    auto data = "hello, server.";
    writeln("Client say: ", data);
    socket.send(data);

    ubyte[1024] buffer = void;
    size_t len = socket.receive(buffer[]);
    writeln("Server reply: ", cast(string)buffer[0..len]);

    socket.shutdown(SocketShutdown.BOTH);
    socket.close();
}

You can add, repair and submit after fork, and improve it together. Thank you.
