Hello,
For tuples, does the fieldNames property have a 1-1
correspondence with the Types property?
It appears that way in my testing:
alias MyData = Tuple!(string,"a",int,"b");
foreach (i, type; MyData.Types){
writeln (MyData.fieldNames[i]," ",type.stringof);
// a string
// b int
}
But I can't figure out for sure from the documentation:
alias fieldNames = staticMap!(extractName, fieldSpecs);
alias Types = staticMap!(extractType, fieldSpecs);
Thanks,
Jordan
It's an implementation detail but I wouldn't expect the order to
ever change.
