Detailed Description

Utility functions for working with std::future collections.

This header provides convenient functions for collecting results from a list of std::future objects. It simplifies the common pattern of waiting for multiple asynchronous operations to complete and gathering their results.

Example Usage

#include <future_utils.H>
#include <async>
 
// Launch multiple async tasks
DynList<std::future<int>> futures;
for (int i = 0; i < 10; ++i)
  futures.append(std::async(std::launch::async, [i] { return i * i; }));
 
// Collect all results (blocks until all complete)
DynList<int> results = get_futures(futures);
// results now contains: 0, 1, 4, 9, 16, 25, 36, 49, 64, 81
