How does awaiting all promises work with promises that contain generators

[CMCDragonkai]

I am intending to use https://github.com/clue/php-buzz-react to asynchronously query a list of remote sites, where each query may optionally require chaining a recursive query into it to perform pagination of the remote site's results.

My blocking system is doing this via a do while loop and generator yield. As I consume each yield, it may in turn perform the next paginated query.

Now that I want to do this asynchronously, I'm concerned as to how a promise yielding a generator of results behave in this case?

$promises = [
    $browser->get('http://example.com/')->then(function ($response) {
        foreach ($response->getParsedBody()['rows'] as $row) {
            yield $row;
        }
    })
];

$allResults = Block\awaitAll($promises, $loop);

Another idea is this, can awaitAll await on a generator of promises? Right now the type is specified as array, why not Traversable?

It appears to work!

Thanks for the confirmation that the above works as expected 👍
