The video tutorial explains the implementation of coroutines with a focus on lazy evaluation. It covers the transition from a basic coroutine to one that performs useful tasks, such as lazy evaluation of values. The tutorial delves into the library developer's perspective, discussing promises, shared state, and the use of shared pointers. It also covers the use of coroutine handles for resumption and destruction, ensuring efficient memory management. The tutorial concludes with the finalization of a coroutine framework, highlighting the importance of documentation and potential extensions for more complex coroutine functionalities.
