Detailed Description

C++20 coroutine task type for async operations.

Provides a lightweight coroutine task type that enables async/await style programming for container operations.

// Example usage:
task<int> compute_async() {
    co_return 42;
}
 
task<void> process() {
    int result = co_await compute_async();
}
