Detailed Description

Returns an observable that attaches a timestamp to each item emitted by the source observable indicating when it was emitted.

Template Parameters

Coordination the type of the scheduler (optional).

Parameters

coordination the scheduler to manage timeout for each event (optional).

Returns: Observable that emits a pair: { item emitted by the source observable, time_point representing the current value of the clock }.

Sample Code: typedef rxcpp::schedulers::scheduler::clock_type::time_point time_point;
using namespace std::chrono;
auto values = rxcpp::observable<>::interval(milliseconds(100))
.timestamp()
.take(3);
time_point start = rxcpp::identity_current_thread().now();
values.
subscribe(
[&](std::pair<long, time_point> v) {
long long int ms = duration_cast<milliseconds>(v.second - start).count();
printf("OnNext: %ld @%lldms\n", v.first, ms);
},
[](std::exception_ptr ep) {
try {
std::rethrow_exception(ep);
} catch (const std::exception& ex) {
printf("OnError: %s\n", ex.what());
}
},
[]() { printf("OnCompleted\n"); });
OnNext: 1 @0ms
OnNext: 2 @100ms
OnNext: 3 @200ms
OnCompleted
