Struct std.datetime.interval.PosInfIntervalRange
A range over a PosInfInterval
. It is an infinite range.
struct PosInfIntervalRange(TP)
if (isTimePoint!TP);
PosInfIntervalRange
is only ever constructed by PosInfInterval
.
However, when it is constructed, it is given a function, func
, which
is used to generate the time points which are iterated over. func
takes a time point and returns a time point of the same type. For
instance, to iterate
over all of the days in the interval PosInfInterval!Date
, pass a
function to PosInfInterval
's fwdRange
where that function took a
Date
and returned a Date
which was one day later. That function would then be used by
PosInfIntervalRange
's popFront
to iterate over the
Date
s in the interval - though obviously, since the
range is infinite, use a function such as std
with it rather
than iterating over all of the dates.
As the interval goes to positive infinity, the range is always iterated over
forwards, never backwards. func
must generate a time point going in
the proper direction of iteration, or a
DateTimeException
will be thrown. So, the time
points that func
generates must be later in time than the one passed to
it. If it's either identical or earlier in time, then a
DateTimeException
will be thrown.
