This library, in the namespace gdr::bits, is a collection of simple basic functions that I often use in my programming. I am putting them here in the hope that they are useful to the C++ community. I wish they were part of the standard library offerings in the bit manipulation space.
The library deliberately uses modules and other contemporary C++ constructs such as concepts. In particular, it does not aim to bend backwards to support previous versions of C++.
Use as you see fit.
