koios

A c++ async runtime library

Quick Start

#include <print>
#include "koios/task.h"
#include "koios/runtime.h"

koios::task<void> coro_task3()
{
    ::std::println("world!");
    co_return;
}

koios::task<int> coro_task2()
{
    ::std::print("koios' ");
    co_await coro_task3();
    co_return 1;
}

koios::task<int> coro_task()
{
    ::std::print("hello ");
    co_return co_await coro_task2();
}

int main()
{
    koios::runtime_init(12);

    int val = coro_task().result();

    return koios::runtime_exit();
}
