very slow as a generator

[teub]

As it's super fast I'm trying to use it as a prime number generator but it seems very slow. Here's my C implementation what did I do wrong

int i = 0;
while (true)
{
	if (is_prime(i))
		break;
	i++;
}
printf("found a prime : %d", i);

I launched this yesterday and it still hasn't found anything

You need to wait a little bit more

Have you considered to rewrite in rust ?
