Hello,
I copy paste the main idea from an article I have written:
contextual async
<https://pythonc.home.blog/2018/12/14/premier-article-de-blog/>
"
Imagine you have some code written for monothread. And you want to include
your code in a multithread environment. Do you need to adapt all your code
which is what you do when you want to migrate to async code ? The answer is
no.
Functionnally these constraints are not justified neither technically
Do we have the tools to do this ? Yes because thanks to boost::context we
can switch context between tasks. When a task suspends, it just calls a
function (the event loop or reactor) to potentially switch to another task.
Just like threads switch contexts…
Async/Await logic has introduced a symetric relation wich introduces
unnecessary contraints. We should just the same logic as thread logic.
"
Read the examples in the article I have developped a prototype in C++ and
everything works perfectly.
My opinion is that sooner or later, it will have to switch to this logic
because chaining async/aswait is a huge contraints and does not make sense
in my opinion.
Maybe I am missing something,
Feel free to give me your feedback.
Regards,
Chris
