This book shows how to use the metaprogramming technique to create data structures and functions that allow computation to happen at compile time. Marius Bancila shows how to use templates to avoid writing duplicate code, and how these are key to creating generic libraries, such as the standard library or Boost, that can be used in multiple programs. 

<ASIN:‎ 1803243457>

Bancila looks at writing complex templates and exploring advanced concepts such as template recursion, template argument deduction, forwarding references, type traits, and conditional compilation. He also covers writing variadic templates and providing requirements to the template arguments with C++20 constraints and concepts.
