OP here, I'm looking for others advice/input on this library. This simple library does 90% of what I need for input vaildation, but I wanted to ask others what else they might add without getting overly complex. Input validation is a research interest of mine. Thanks for looking.
Not really a C++ dev, but why are there so many std:: prefixes? why not just use namespace?
That's generally a no no in header files/libraries. If someone does that in a header it brings the entire namespace into global scope. IMO, I like very explicit code so I always use full qualifiers. Short cuts bother me, but that's just my personal preference.
