Tuples: .tupleof property

Explore the use of the .tupleof property in D programming to access members of user-defined types or objects. Understand that .tupleof returns references to members, enabling efficient data handling similar to structs, and learn how tuples support indexing, slicing, and loop unrolling.

We'll cover the following...

.tupleof property

.tupleof represents the members of a type or an object. When applied to a user- defined type, .tupleof provides access to the definitions of the members of that type:

D
import std.stdio;



struct S {

    int number;

    string message;

    double value;

}



void main() {

    foreach (i, MemberType; typeof(S.tupleof)) {

        writefln("Member %s:", i);

        writefln("  type: %s", MemberType.stringof);



        string name = S.tupleof[i].stringof;

        writefln("  name: %s", name);

    }

}

S.tupleof appears in two places in the program. First, the types of the elements are obtained by ...
