Question

I’m messing with core.time.Durations – in particular, I’m trying to properly get number of full minutes in “2 days and 1 hour” Duration. As it have cleared, get!"minutes" returns number of minutes without hours, days and weeks (e.g. 0 in this case), so it’s inappropriate for me, because I expect answer of 2940.

I’ve looked into sources and found core.time.getUnitsFromHNSecs function, which does exactly what I need, but it’s private to core.time and uses private field _hnsecs of Duration objects.

Of course, it’s possible to do

long minutes_in_duration(Duration d) {
    return (d.get!"minutes"() + d.get!"hours"() * 60 + 
            d.get!"days"() * 24 * 60 + d.get!("weeks") * 7 * 24 * 60);
}

but this is clumsy as hell. Is there better way to do the same thing without scattering away Duration‘s guts?

Answer 1

More thorough reading through source revealed overlooked .total!"unit" property, which does exactly what it should.
