Let i have code:

Clock.currTime.to!DateTime.Interval!DateTime( 24.hours ).fwdRange(
h=>h+1.hours ).writeln;

Now if i want to set the minute=0 and second=0 without breaking chain,
what i should do?


I think about somewhat like:

with( Clock.currTime.to!DateTime){
 minute=0;
 second=0
}.Interval!DateTime( 24.hours ).fwdRange( h=>h+1.hours ).writeln;

But it is wrong, because 'with' not return me anything.

I would probably write a function:

import std.datetime;
import std.stdio;
import std.range;
import std.conv;

DateTime hourPrecision(DateTime dt) {
    dt.minute = 0;
    dt.second = 0;
    return dt;
}

void main() {
Clock.currTime.to!DateTime.hourPrecision.Interval!DateTime( 24.hours ).fwdRange( h=>h+1.hours ).writeln;
}
