fusion

Exception-free error handling library.

Example

#include <fusion/result.h>
#include <iostream>

auto divide(const int a, const int b) -> sz::result<int, std::invalid_argument> {
    if (a == 0 || b == 0) {
        return std::invalid_argument{"divide by zero"};
    }
    return a / b;
}

int main() {
    if (auto result = divide(64, 8); result.has_value()) {
        std::cout << "64 / 8 = " << result.get() << std::endl;
    } else {
        std::cerr << "error: " << result.get_error().what() << std::endl;
    }
    return 0;
}
