Detailed Description

Main header for the qtty C++ wrapper library.

This header provides a modern, type-safe C++ interface to the qtty-ffi library. It includes:

• Template-based Quantity class with compile-time unit checking
• Operator overloading for natural arithmetic syntax
• User-defined literals for convenient quantity creation
• Support for length, time, angular, and compound (velocity) units

Usage example:

using namespace qtty;
 
// Create quantities using constructors or literals
Meter distance(1000.0);
auto time = 20.0_s;
 
// Perform arithmetic operations
auto doubled = distance * 2.0;
 
// Convert units
Kilometer km = distance.to<Kilometer>();
 
// Create compound units (velocity)
auto velocity = distance / time;
