Error when "closing" a time interval

[caxelrud]

I am getting the following error:

source = interval(10000)
close(source) 
ERROR: MethodError: no method matching close(::TimerObservable{Int64})

The close function is not (and should not be) implemented for interval because there is nothing to close initially. The interval only starts when you call subscribe!

source = interval(10000)

This line merely sets up the data structure needed for subscribe!. The interval begins with the following line:

subscription = subscribe!(source, logger()) # starts the interval

You can then use unsubscribe! to stop the interval, which will automatically call close:

unsubscribe!(subscription)  # Automatically closes the interval
