Zedio is an event-driven header library for writing asynchronous applications in modern C++:

Feature:

• Multithreaded, work-stealing based task scheduler. (reference tokio)
• Proactor event handling backed by io_uring.
• Zero overhead abstraction, no virtual, no dynamic

Sub library:

• I/O
• NetWorking
• FileSystem
• Time
• Sync
• Log

It's being developed, if you're interested in zedio and want to participate in its development, see contributing

Example

// An echo server
// Ignore all errors
#include "zedio/core.hpp"
#include "zedio/net.hpp"

using namespace zedio;
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", 9999).value();
    auto listener = TcpListener::bind(addr).value();
    while (true) {
        auto [stream, addr] = (co_await listener.accept()).value();
        spawn(process(std::move(stream)));
    }
}

auto main() -> int {
    // zedio::runtime::CurrentThreadBuilder::default_create().block_on(server());
    zedio::runtime::MultiThreadBuilder::default_create().block_on(server());
}
