std::discr...param_type(3)

🎀 std::discr...param_type(3) 🎀

okay bestie, so this is a page straight out of the Library Functions Manual, section 3, and it's all about std::discrete_distribution< _IntType >::param_type — the little parameter-type struct that lives inside your discrete distribution. it's niche, it's cute, it's giving template energy 💅

---

✨ NAME ✨

std::discrete_distribution< _IntType >::param_type — the parameter type for std::discrete_distribution< _IntType >. no cap, that's literally the whole name.

---

🌸 SYNOPSIS 🌸

first thing first, you gotta pull it in:

#include <random>

👑 Public Types

one (1) type, and it's serving:

• typedef discrete_distribution< _IntType > distribution_type — a lil alias so you don't have to keep typing out discrete_distribution< _IntType > like a menace.

🦋 Public Member Functions

here's the whole roster, bestie, all of it, not skipping a single one:

• template<typename _InputIterator> param_type(_InputIterator __wbegin, _InputIterator __wend) — build one from a range of weights, __wbegin up to __wend.
• param_type(const param_type &) = default — the copy constructor. it's defaulted, she's just like that.
• param_type(initializer_list< double > __wil) — build one straight from an initializer_list< double > called __wil.
• template<typename _Func> param_type(size_t __nw, double __xmin, double __xmax, _Func __fw) — build one with __nw weights, where each weight k comes from calling __fw(__xmin + k * (__xmax - __xmin) / __nw) — that's a _Func doing the work.
• param_type & operator=(const param_type &) = default — assignment operator, also defaulted, also unbothered.
• std::vector< double > probabilities() const — hands you back the probabilities as a std::vector< double >. iconic.

🫶 Friends

yes she has friends, and we love that for her:

• class discrete_distribution< _IntType > — the distribution herself is a friend.
• bool operator==(const param_type &__p1, const param_type &__p2) — compare two param types for equality. two args, __p1 and __p2, returns bool.

💜 Detailed Description 💜

template<typename _IntType = int>
struct std::discrete_distribution< _IntType >::param_type

and the description, verbatim vibe: "Parameter type." that's it. that's the whole description. short, sweet, main character energy 😭

so yeah, that's the whole page fr fr 💖 this lil corner of the libstdc++ manual, section 3, brought to you by libstdc++ and its Doxygen-generated source code — no date on this one bestie, the footer keeps it mysterious 🌈✨ bye ily, go read your <random> header 🦋
