Overview

Zedio is a event-driven platform for writing asynchronous applications with the C++, At a high level, it provides a few major components:

• A multithreaded, work-stealing based task scheduler.(reference tokio)
• A proactor backed by linux systems's io_uring.
• Asynchronous TCP and UDP sockets.

Install && Compile Tests

Compiler requirements

Your compiler must support C++23. My compiler is GCC 13.1.0.

Zedio is header only,and you can copy zedio into your project,or install it via CMake.

1. clone zedio

git clone https://github.com/8sileus/zedio
cmake -B build
cd build

2. install

cmake --install . # --prefix ./user_defined_install_path 

3. compile tests

cmake --build . # -j num_thread
ctest .

Example

Writing an echo server using Zedio

// Ignore all errors
#include "zedio/async.hpp"
#include "zedio/net.hpp"

using namespace zedio::async;
using namespace zedio::net;

auto process(TcpStream stream) -> Task<void> {
    char buf[1024];
    while (true) {
        auto len = (co_await stream.read(buf)).value();
        if (len == 0) {
            break;
        }
        co_await stream.write_all({buf, len});
    }
}

auto server() -> Task<void> {
    auto addr = SocketAddr::parse("localhost", 9898).value();
    auto listener = TcpListener::bind(addr).value();
    while (true) {
        auto [stream, peer_addr] = (co_await listener.accept()).value();
        spawn(process(std::move(stream)));
    }
}

auto main() -> int {
    auto runtime = Runtime::create();
    runtime.block_on(server());
    return 0;
}
