Hi All,
It is possible to store struct in a array ans use the same in
csvReader e.g.
import std.stdio;
import std.container.array;
void main () {
Array!string a;
struct Layout { string name; int value; double other; }
a.insert(Layout);
auto record =
uFile.byLineCopy().joiner("\n").csvReader!(Tuple!a[0]))
foreach (record; records)
{
writeln(record.name);
writeln(record.value);
writeln(record.other);
}

Hi All,
Was able to find on hot to store a struct in an array, but not
able to use that array in csvReader
Program:
import std.algorithm: joiner;
import std.container.array;
import std.csv: csvReader;
import std.stdio: File, writeln;
import std.typecons: Tuple, tuple;
void main () {
auto fName =
"C:\\Users\\bheev1\\Desktop\\Current\\Script\\Others\\Table1.csv";
auto uFile = File(fName, "r");
struct T1 { string Name; string Country; int Age; }
Array!T1 T1s;
foreach (record;
uFile.byLineCopy().joiner("\n").csvReader!(Tuple!T1s))
writeln(record);
}
Error:
C:\D\dmd2\windows\bin\..\..\src\phobos\std\typecons.d(523):
Error: template instance parseSpecs!(T1s) cannot use local 'T1s'
as parameter to non-global template
