libuv wrapper in C++11. /libuv C++11封装。

uv-cpp

Language Translations:

• Englishi
• 简体中文

---

Features

• C++11 style callbacks instead of C： You can use class member functions or lambda as callbacks.
• TCP and UDP wrapper.
• TimerandTimerWheel：Heartbeat timeout judgment mechanism with time complexity of O(1).
• Async：Optimized the problem of calling multiple times, perhaps only once, compared to the libuv's async.
• PacketandPacketBuffer：Send and receive packet data, used to resolve TCP stubs/stickers.
• Log interface.

Simple test

environment：Intel Core i5 6402 + ubuntu14.04.5 + gcc5.5.0 + libuv1.22.0 + O2优化

Quick start

#include <iostream>
#include <uv/uv11.h>


int main(int argc, char** args)
{
    //event's loop
    //uv::EventLoop* loop = new uv::EventLoop();
    //or
    uv::EventLoop* loop = uv::EventLoop::DefalutLoop();
    //Tcp Server
    uv::SocketAddr serverAddr("0.0.0.0", 10002, uv::SocketAddr::Ipv4);
    uv::TcpServer server(loop, serverAddr);
    server.setMessageCallback(
        [](std::shared_ptr<uv::TcpConnection> conn, const char* data , ssize_t size)
    {
        std::cout << std::string(data, size) << std::endl;
        std::string str("hex :");
        uv::LogWriter::ToHex(str, data, size);
        std::cout << str << std::endl;
        conn->write(data, size,nullptr);
    });
    server.start();

    //Tcp Client
    uv::TcpClient client(loop);
    client.setConnectStatusCallback(
        [&client](uv::TcpClient::ConnectStatus status)
    {
        if (status == uv::TcpClient::ConnectStatus::OnConnectSuccess)
        {
            char data[] = "hello world!";
            client.write(data, sizeof(data));
        }
        else
        {
            std::cout << "Error : connect to server fail" << std::endl;
        }
    });
    client.connect(serverAddr);

    loop->run();
