kotlin coroutines - withContext vs suspendCoroutine

i was wondering since both withContext and suspendCoroutine are suspend functions is there any difference betweeen them other then the fact that suspendCoroutine offers a continuation so you can control when it resumes or cancels if we use suspendCancellableCoroutine variation. I would say both can be used to stop making callbacks (which is one advantage of coroutines). is there any major difference ?

Actually only suspendCoroutine can be used to translate a callback-based API into coroutines. withContext doesn't have the effect of suspending a coroutine, but temporarily changing its context (this is mainly about changing the dispatcher). The coroutine immediately continues in the other context and then comes back to the caller's context.
