Detailed Description

C++20 coroutine support with generator pattern implementation.

This file implements a type-safe, lazy-evaluation generator pattern using C++20 coroutines. The generator provides a convenient way to create and consume sequences of values with minimal memory overhead and efficient suspension/resumption semantics.

Key Features:

• Lazy evaluation: Values are generated on-demand
• Exception safety: Proper exception propagation through coroutine boundaries
• Iterator support: Compatible with range-based for loops and STL algorithms
• Move semantics: Efficient transfer of coroutine state
• Resource management: Automatic cleanup of coroutine handles
• Type safety: Compile-time type checking for generated values

Note

The generator suspends after each yielded value, allowing consumers to control the execution flow and memory usage.

Coroutine state is automatically destroyed when the generator goes out of scope, preventing resource leaks.
