Detailed Description

Coroutine-based task.

This file contains the definition of a coroutine-based task class template. The task class allows for the creation of coroutine-based tasks that produce values of a specified type. It provides an interface for handling asynchronous operations and managing the state of the coroutine.

Example:

wwa::coro::task<int> task1()
{
    co_return 123;
}
 
wwa::coro::task<int> task2()
{
    co_return 456;
}
 
wwa::coro::task<int> sum()
{
    const auto a = co_await task1();
    const auto b = co_await task2();
    co_return a + b;
}
 
wwa::coro::task<> print()
{
    std::cout << "The result is " << co_await sum() << "\n";
}
