To go through all the elements in the producer, you can use the  consumeEach() function, as follows for example:

val context = newSingleThreadContext("myThread")

val producer = produce(context) {
    for (i in 0..9) {
        send(i)
    }
}

This producer will produce up to 10 numbers; to retrieve all of them we can simply call consumeEach() on the producer:

fun main(args: Array<String>) {
    producer.consumeEach {
        println(it)
    }
}
