Detailed Description

All values are queued and delivered using the scheduler from the supplied coordination.

Template Parameters
Coordinationthe type of the scheduler.
Parameters
cnthe scheduler to notify observers on.
Returns
The source observable modified so that its observers are notified on the specified scheduler.
Sample Code
printf("[thread %s] Start task\n", get_pid().c_str());
auto values = rxcpp::observable<>::range(1, 3).
map([](int v){
printf("[thread %s] Emit value %d\n", get_pid().c_str(), v);
return v;
});
values.
[](int v){printf("[thread %s] OnNext: %d\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());
[thread 47481267428736] Start task
[thread 47481267428736] Emit value 1
[thread 47481267428736] Emit value 2
[thread 47481267428736] Emit value 3
[thread 47481303181056] OnNext: 1
[thread 47481303181056] OnNext: 2
[thread 47481303181056] OnNext: 3
[thread 47481303181056] OnCompleted
[thread 47481267428736] Finish task
Invoking rxcpp::observable::subscribe_on operator, instead of observe_on, gives following results:
[thread 47481267428736] Start task

[thread 47481313687296] OnNext: 1
[thread 47481313687296] Emit value 2
[thread 47481313687296] OnNext: 2
[thread 47481313687296] Emit value 3
[thread 47481313687296] OnNext: 3
[thread 47481313687296] OnCompleted
[thread 47481267428736] Finish task
