run_awaitable.cpp

Shows how to use run_awaitable to turn any awaitable into an eager coroutine that runs synchronously from the caller's perspective.

#include <iostream>
 
#include "eager_task.h"
#include "task.h"
 
namespace {
 
wwa::coro::task<int> async_increment(int v)
{
    co_return v + 1;
}
 
wwa::coro::task<> display(int v)
{
    auto result = co_await async_increment(v);
    std::cout << "Result: " << result << "\n";
}
 
}  // namespace
 
int main()
{
    wwa::coro::run_awaitable(display, 2);
 
    // Expected output:
    // Result: 3
 
    return 0;
}
