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

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

Boost Asio is a library for asynchronous input/output, while std::future is used for managing asynchronous tasks. Boost Asio provides more control over I/O operations, whereas std::future is simpler for handling task results.

When should I use Boost Asio instead of std::future?

Use Boost Asio when you need fine-grained control over asynchronous I/O operations, like networking or file handling. std::future is better for simpler task management.

Can you give an example of using Boost Asio?

Sure! Here's a simple example: you can use Boost Asio to create a TCP server that handles multiple connections asynchronously.

What are the performance implications of using one over the other?

Boost Asio can be more efficient for I/O-bound tasks due to its event-driven model, while std::future may introduce overhead for task management in CPU-bound scenarios.
