public class GlobalScope implements CoroutineScope
A global interface CoroutineScope not bound to any job.
Global scope is used to launch top-level coroutines which are operating on the whole application lifetime and are not cancelled prematurely. Another use of the global scope is operators running in Dispatchers.Unconfined, which don't have any job associated with them.
Application code usually should use application-defined interface CoroutineScope, using
DeferredKt.async or BuildersKt.launch
on the instance of class GlobalScope is highly discouraged.
Usage of this interface may look like this:
fun ReceiveChannel.sqrt(): ReceiveChannel = GlobalScope.produce(Dispatchers.Unconfined) {
for (number in this) {
send(Math.sqrt(number))
}
}
