Detailed Description

Make new observable with items skipped until on_next occurs on the trigger observable or until the specified time. skip_until takes (TriggerObservable, optional Coordination) or (TimePoint, optional Coordination)

Template Parameters

TriggerSource	the type of the trigger observable.
Coordination	the type of the scheduler (optional).

Parameters

t	an observable that has to emit an item before the source observable's elements begin to be mirrored by the resulting observable.
cn	the scheduler to use for scheduling the items (optional).

Returns

An observable that skips items from the source observable until the second observable emits an item or the time runs out, then emits the remaining items.

Sample Code

    auto source = rxcpp::observable<>::interval(std::chrono::milliseconds(10)).take(7);
    auto trigger = rxcpp::observable<>::timer(std::chrono::milliseconds(25));
    auto values = source.skip_until(trigger);
    values.
        subscribe(
            [](long v){printf("OnNext: %ld\n", v);},
            [](){printf("OnCompleted\n");});

OnNext: 4
OnNext: 5
OnNext: 6
OnNext: 7
OnCompleted

Sample Code

    printf("[thread %s] Start task\n", get_pid().c_str());
    auto source = rxcpp::observable<>::interval(std::chrono::milliseconds(10)).take(7).map([](long v){
        printf("[thread %s] Source emits, value = %ld\n", get_pid().c_str(), v);
        return v;
    });
    auto trigger = rxcpp::observable<>::timer(std::chrono::milliseconds(25)).map([](long v){
        printf("[thread %s] Trigger emits, value = %ld\n", get_pid().c_str(), v);
        return v;
    });
    auto values = source.skip_until(trigger, rxcpp::observe_on_new_thread());
    values.
        as_blocking().
        subscribe(
            [](long v){printf("[thread %s] OnNext: %ld\n", get_pid().c_str(), v);},
            [](){printf("[thread %s] OnCompleted\n", get_pid().c_str());});
    printf("[thread %s] Finish task\n", get_pid().c_str());
