Hello,
I have an array of objects of class C which contain a id member.
I want to figure out if all the id members are unique using
functional primitives.
For example, if I have:
class C
{
int id;
}
and an array of C 'Cs';
My idea was to do:
auto ids = Cs.map!(c => c.id);
assert(equal(ids.sort().uniq(), ids.sort()));
But it doesn't compile because I can't can call sort on ids.
Any idea why ? and how to solve my initial problem, which is to
check all ids are unique.
Regards,
Dorian
