I created a string system faster than the std::string!

Am I reinventing the wheel?

I deal with data for billions of times repeatedly, so it was necessary to reduce the time and resources consumed in those transactions, and for this I programmed this simple system, which in turn saved a lot of time and resources unlike other systems.

In the end, I tell you that this system is 5 times faster than the std::string system, and provides all the features that this system provides, so this system is definitely the best at all.

I'm not the type to talk a lot but wanted to share what I accomplished with you guys.

Performance test script compared to the std::string:

#include "xstr.h"#include <string>#include <chrono>int main(){std::cout << "x::xstr";std::chrono::steady_clock::time_point begin = std::chrono::steady_clock::now();for(int i = 0; i < 100000; i++) { xstr x = "Hello World"; x += " Extra String"; }std::chrono::steady_clock::time_point end = std::chrono::steady_clock::now(); std::cout << "
\033[1;30mExecute Time: " << std::chrono::duration_cast<std::chrono::microseconds>(end - begin).count() / 1000 << "s \033[0m
"; std::cout << "std::string";std::chrono::steady_clock::time_point begin2 = std::chrono::steady_clock::now();for(int i = 0; i < 100000; i++) { std::string x = "Hello World"; x += " Extra String"; }std::chrono::steady_clock::time_point end2 = std::chrono::steady_clock::now(); std::cout << "
\033[1;30mExecute Time: " << std::chrono::duration_cast<std::chrono::microseconds>(end2 - begin2).count() / 1000 << "s \033[0m
";}

result

x::xstrExecute Time: 6s std::stringExecute Time: 38s
