Infinite loop stops yielding at some point about async-executor HOT 4 CLOSED

The run() function runs the main future. When the main future is idle (because it's waiting for I/O or timers or something), it runs other tasks on the executor. When the main future is done, it exits.

If you don't call run() at all, spawned tasks will simply be waiting in the executor's task queue.

If you give the main future a timer of 1 hour, it will run spawned tasks for 1 hour and then stop everything.

If you give it an unresolved future, it will run spawned tasks forever.

Ah yes, that's completely normal :)

Note that the Executor::run() function doesn't run until all tasks have been processed - it only runs until the main future passed to it completes. So if you do ex.run(yield_now()), then some tasks will be run but then as soon as yield_now() completes, the whole run() stops.

At that point, you can call run() again with a new future if you want.

Okay I see, does it means that the main future controls all the runtime of the others tasks spawned inside the executor?
So if I give a Timer of 1 hour, it will run all spawned tasks for 1 hour, if I give an unresolved future then it will run forever?

Okay got it! :)
It’s more clear now, thank you! 👍
I close the issue. ;)
