C++: Boost Asio vs. std::async

What are the main differences between Boost Asio and std::async in C++?

Boost Asio is a library for asynchronous input/output operations, while std::async is a standard library feature for running tasks asynchronously. Boost Asio provides more control over I/O operations and is more suitable for network programming, whereas std::async is simpler and easier to use for general asynchronous tasks.

Which one should I use for a network application?

For a network application, Boost Asio is generally the better choice due to its extensive features for handling asynchronous I/O, timers, and more. It allows for fine-tuned control over the networking aspects.

Are there any performance differences between them?

Yes, Boost Asio can offer better performance for I/O-bound applications because it is designed specifically for that purpose. std::async may introduce overhead due to its task management and thread handling.

Can I use both in the same project?

Yes, you can use both Boost Asio and std::async in the same project. Just be mindful of how they manage threads and resources to avoid potential conflicts.
