IteratorStream	/iterator-stream

IteratorStream allows converting an Amp\Iterator that yields strings into an InputStream.

$inputStream = new IteratorStream(new Producer(function (callable $emit) {
    for ($i = 0; $i < 10; $i++) {
        yield new Delayed(1000);
        yield $emit(".");
    }
});
