Qt Asynchronous Event Loop

This library integrates Boost.Coroutine2 into Qt.

You can await in an event loop, instead of creating QEventLoop to wait something done.

Example

auto task = new qtael::Async([](const qtael::Await & await) -> void {
    QNetworkAccessManager nasm;
    QUrl url{"https://www.google.com/"};
    QNetworkRequest request{url};

    auto reply = nasm.get(request);
    // NOTE yield to main event loop until the request finished
    await(reply, &QNetworkReply::finished);

    auto data = reply->readAll();
    reply->deleteLater();

    qDebug() << data;
});

// NOTE When the asynchronous function finished (i.e. reaches end or return),
// signal `finished()` will be emitted.
task->connect(task, SIGNAL(finished()), SLOT(deleteLater()));
// NOTE start this task, and it will not block the event loop
task->start();
