Introduction
Explore how templates allow you to write generic and reusable code in D, covering function, struct, and class templates with type parameters. Understand how templates replace repetitive overloads with scalable, type-independent solutions, making algorithms and data structures more flexible.
We'll cover the following...
Templates
Templates are the feature that allows us to describe the code as a pattern for the compiler to generate program code automatically. Parts of the source code may be left to the compiler to be filled in until that part is actually used in the program.
Templates are very useful, especially in libraries, because they enable writing generic algorithms and data structures, instead of tying them to specific types.
Compared to the template support in other languages, D’s templates are very powerful and extensive. We will not get into all of the ...
