TaskThreadingImpl with dispatchers instead of schedulers

TaskThreadingImpl.kt

class TaskThreadingImpl @Inject constructor() : TaskThreading {
  // declaration of dispatchers
  private val computationCoroutineDispatcher: CoroutineDispatcher = Default 
  private val ioCoroutineDispatcher: CoroutineDispatcher = IO
  private val mainCoroutineDispatcher: CoroutineDispatcher = Main
			
  // other schedulers here
  // dispatchers:
  override fun uiDispatcher(): CoroutineDispatcher = mainCoroutineDispatcher
  override fun ioDispatcher(): CoroutineDispatcher = ioCoroutineDispatcher
  override fun computationDispatcher(): CoroutineDispatcher = computationCoroutineDispatcher
}
