QPromise::delay

Since: 0.2.0

QPromise<T>::delay(int msec) -> QPromise<T>

This method returns a promise that will be fulfilled with the same value as the input promise and after at least msec milliseconds. If the input promise is rejected, the output promise is immediately rejected with the same reason.

QPromise<int> input = {...}
auto output = input.delay(2000).then([](int res) {
    // called 2 seconds after `input` is fulfilled
});
