Anyone have a simple implementation for a suspending CountDownLatch?

What is your case for this? Maybe existing suspend Semaphore or other primitive will work for you

I have a suspending connect function and after I connect and send credentials I want to suspend until I received a success but this happens in a generic data handler which will unlatch

Semaphore can work there

thank you looking at docs now

Also if you have only one lock just use suspend Mutex

Also coroutineScope can solve many of the concerns of CDL though maybe not this specific one
