lzc-coro - LaZyCoders COROutine library

This small library have the objective of understand coroutine facility. It is too a playground to test some ideas about how coroutines could work.

The basics

This library only implements the task: a coroutine that can do co_await.

All tasks can be awaitable and are created stopped. That means a coroutine do not start executing code until the call to operator() of the task is called.

    other_task->>async_function: co_await
    Note over other_task,async_function: The coroutine wait until completion<br/>and continues in the original thread
    async_function-->>other_task:resume()
    other_task-->>some_task:resume()
    some_task-->>main:future.get()
