std::discar...block_engine(3)

🦋 std::discard_block_engine::discard_block_engine 🦋

okay bestie, welcome to the C++ Standard Libary manual — section 3, no cap. The page header is literally std::discar...block_engine(3) (yes, with the lil truncated vibe, iykyk), and we're talking about the constructor of std::discard_block_engine::discard_block_engine. It's giving “engine adaptor origin story” and I'm obsessed. 💖

🌸 NAME 🌸

std::discard_block_engine::discard_block_engine — std::discard_block_engine::discard_block_engine

✨ Synopsis ✨

discard_block_engine();                           (1) (since C++11)
explicit discard_block_engine( result_type s );   (2) (since C++11)
template< class Sseq >                            (3) (since C++11)
explicit discard_block_engine( Sseq& seq );
explicit discard_block_engine( const Engine& e ); (4) (since C++11)
explicit discard_block_engine( Engine&& e );      (5) (since C++11)

Constructs new pseudo-random engine adaptor. periodt. 🫶

1. Default constructor. The underlying engine is also default-constructed. iconic default behavior, ngl. ✨
2. Constructs the underlying engine with s. slay. 💅
3. Constructs the underlying engine with seed sequence seq. This constructor only participates in overload resolution if Sseq qualifies as a SeedSequence. In particular, this constructor does not participate in overload resolution if Sseq is implicitly convertible to result_type. read that twice, bestie — it's the main character caveat. 🚨
4. Constructs the underlying engine with a copy of e. copy-paste but make it engine. 🎀
5. Move-constructs the underlying engine with e. e holds unspecified, but valid state afterwards. so it's still alive, just lowkey not the same vibe anymore. 😭

🎀 Parameters 🎀

• s — integer value to construct the underlying engine with. a whole number, doing engine stuff. 🔢
• seq — seed sequence to construct the underlying engine with. seed-sequence energy fr fr. 🌱
• e — pseudo-random number engine to initialize with. the engine being copied or moved into the situation. 🔥

💜 Example 💜

this page doesn't actually show an example block, bestie — it just goes straight to the footer vibe. no cap, that's the whole content. 💀

okay that's the page, bestie — source/version is http://cppreference.com, date is 2024.06.10, and the std::discar...block_engine(3) footer energy is officially wrapped. mwah, go construct something cute. 💋🦋
