asyncMain
fun <T> CoroutineScope.asyncMain(context: CoroutineContext = EmptyCoroutineContext, start: CoroutineStart = CoroutineStart.DEFAULT, block: suspend CoroutineScope.() -> T): Deferred<T>
Content copied to clipboard
Creates a coroutine and returns its future result as an implementation of Deferred.
Uses the maindispatcher.
The specific dispatcherProvider instance to be used is determined after the context parameter has been folded into the receiver's context.
The selected DispatcherProvider is essentially the first non-null result from:
the context parameter
the receiver CoroutineScope's coroutineContext
DefaultDispatcherProvider.get Extracts the DispatcherProvider from the CoroutineScope receiver
