Advanced Programming Techniques in D

Template Specializations and Meta Programming

Explore the concept of template specializations and meta programming in D. Understand how to use templates for compile-time code generation, including recursive template instantiations, and how meta programming can move operations from run time to compile time for better performance and code optimization.

We'll cover the following...

Template specializations

We have discussed template specializations in the templates chapter. Like type parameters, other kinds of template parameters can also be specialized. The following is the general definition of a template and its specialization for 0:

D
void foo(int value)() {

    // ... general definition ...

}



void foo(int value : 0)() {

    // ... special definition for zero ...

}

We will take advantage of template specializations in the meta programming section ...
