Use coroutineScope with three async calls. If one child fails, the scope cancels its siblings and rethrows, so you handle the error in one place.
val checkout = try { coroutineScope { val user = async { api.user() } val cart = async { api.cart() } val offers = async { api.offers() } Checkout(user.await(), cart.await(), offers.await()) } } catch (e: IOException) { null // one failed: the others were cancelled }
Follow-up: what changes with supervisorScope?
Everything for the Android rounds, in one place.
