Is there at least one way to impl async_main call sync_drop call async_drop?

background

When I

• try to impl async_main call sync_drop call async_drop

I found

• Handle::current().block_on

leads to

Cannot start a runtime from within a runtime. This happens because a function (like `block_on`) attempted to block the current thread while the thread is being used to drive asynchronous tasks.

question

After searching, according to my current confusing understanding

• there is no way to impl async_main call sync_drop call async_drop.

1. Am I correct?

2. If I am correct, is there a feature request, that tokio should provide at least one way to impl async_main call sync_drop call async_drop?

You can use block_in_place, but it's not great. It is best to not use destructors for this purpose.
