task.cpp

Example of how to use tasks.

#include <iostream>
 
#include "eager_task.h"
#include "task.h"
 
namespace {

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";
}
 
}  // namespace
 
int main()
{
    wwa::coro::run_awaitable(print);
 
    // Expected output:
    // The result is 579
 
    return 0;
}
