suspend inline fun <T> suspendCoroutine(
crossinline block: (Continuation<T>) -> Unit
Obtains the current continuation instance inside suspend functions and suspends the currently running coroutine.
In this function both Continuation.resume and Continuation.resumeWithException can be used either synchronously in the same stack-frame where the suspension function is run or asynchronously later in the same thread or from a different thread of execution. Subsequent invocation of any resume function will produce an IllegalStateException.
