Do all suspend functions have a Job?

Is coroutineContext[Job]!! safe to use inside a suspend function? Do all suspend functions have a Job?

No, not all suspend functions have a job.

coroutineContext is general Kotlin mechanism to pass coroutines-related objects through suspend call-chain transparently and Job is kotlinx.coroutines specific abstraction.

If you've launched a coroutine via any kotlinx.coroutines builder which supports Job (e.g. using async, launch or produce. You can check specific builder documentation to check whether it supports Job), then you have Job in your coroutineContext.

But if you launched coroutine in another way, e.g. using stdlib buildSequence, then coroutine context will not contain job.
