Set task execution to happen on the main thread #169
Description
Hello,
I'm investigating the use of this awesome library for a project I'm working on. More specifically I need to be able to run some of the tasks on the main thread because of limitation of the framework I'm using.
Let's say I have the following graph (sorry for the bad pseudo code, I hope you understand)
main_thread(a) <= raft::kset( main_thread(b), c )
b and c can be parallelized but I want for example a and b to run on the main thread, is it possible to express such condition?
On the main thread a is executed then b and c must be executed but b must also run in the main thread, so it can submit c to some thread pool, provide input from a and keep executing b in the same thread.
