std.datetime.neg_inf_interval.span - multiple declarations

Function NegInfInterval.span

Returns an interval that covers from the earliest time point of two intervals up to (but not including) the latest time point of two intervals.

Prototype

NegInfInterval span(
  Interval!TP interval
) const pure;

Parameters

NameDescription
interval The interval to create a span together with this interval.

Throws

DateTimeException if the given interval is empty.

Note

There is no overload for span which takes a PosInfInterval, because an interval going from negative infinity to positive infinity is not possible.

Examples

assert(NegInfInterval!Date(Date(2012, 3, 1)).span(
            Interval!Date(Date(1990, 7, 6), Date(2000, 8, 2))) ==
       NegInfInterval!Date(Date(2012, 3 , 1)));

assert(NegInfInterval!Date(Date(2012, 3, 1)).span(
            Interval!Date(Date(1999, 1, 12), Date(2015, 9, 2))) ==
       NegInfInterval!Date(Date(2015, 9 , 2)));

assert(NegInfInterval!Date(Date(1600, 1, 7)).span(
            Interval!Date(Date(2012, 3, 11), Date(2017, 7, 1))) ==
       NegInfInterval!Date(Date(2017, 7 , 1)));
