std::unifor...::operator()(3)

🎀 std::unifor...::operator() 🎀

okay bestie, welcome to the C++ Standard Libary manual page for std::uniform_int_distribution::operator() — yes, the header is all truncated like std::unifor...::operator()(3), but the full name is right down below. It’s giving “I’m a template operator and I know it” energy 💅✨

🌸 NAME 🌸

std::uniform_int_distribution::operator() — std::uniform_int_distribution::operator().

Yes, that’s the name repeated. Iconic. We move. 💖

✨ Synopsis ✨

Two template flavors, both (since C++11) — here’s the exact synopsis, bestie:

          template< class Generator >                                       (1)
       (since C++11)
          result_type operator()( Generator& g );
          template< class Generator >                                       (2)
       (since C++11)
          result_type operator()( Generator& g, const param_type& params );

So what do these do? They generate random numbers that are distributed according to the associated probability function. The entropy is acquired by calling g.operator(). Version (1) uses the associated parameter set; version (2) uses params. The associated parameter set is not modified — important vibe check, no sneaky edits. 🫶

🦋 Parameters 🦋

• g — a uniform random bit generator object.
• params — distribution parameter set to use instead of the associated one. Slay.

👑 Type requirements 👑

• Generator must meet the requirements of UniformRandomBitGenerator. That’s the whole requirement, bestie — no cap. ✨

🍓 Return value 🍓

The generated random number. Periodt. 💖

🌈 Complexity 🌈

Amortized constant number of invocations of g.operator(). So it’s chillin’ at amortized constant — literally what the page says. 💅
