- Written in modern C++17
- Compile-time
- std::string-like interface
#include "static_string.h"
#include <iostream>
int main()
{
constexpr cts::static_string<char, 14> str = "Compile-time ";
constexpr cts::static_string<char, 7> str2 = "string";

NOTE: When initializing the string object on instantiation, the template arguments can be deduced, thus, can be omitted.
