sync_generator_adapter.cpp

Example of adapting an async_generator to use with std::ranges.

#include <iostream>
#include <ranges>
 
#include "async_generator.h"
#include "sync_generator_adapter.h"
 
namespace {

wwa::coro::async_generator<int> async_iota(int start = 0)
{
    for (int i = start;; ++i) {
        co_yield i;
    }
}
 
}  // namespace
 
int main()
{
    wwa::coro::sync_generator_adapter sync_iota(async_iota(10));
 
    for (const auto& n : sync_iota | std::views::take(5)) {
        std::cout << n << "\n";
    }
 
    // Expected output:
    // 10
    // 11
    // 12
    // 13
    // 14
 
    return 0;
