Dispatchers.kt

object Dispatchers {  
    val Default: CoroutineDispatcher = createDefaultDispatcher()  
    val Main: MainCoroutineDispatcher get() = MainDispatcherLoader.dispatcher  
    val Unconfined: CoroutineDispatcher = kotlinx.coroutines.Unconfined  
    val IO: CoroutineDispatcher = DefaultScheduler.IO
