💖 std::chrono::duration< _Rep, _Period > 💖

okay so bestie, this is the manual page for std::chrono::duration< _Rep, _Period > from the C++ standard library, section 3cxx. it's literally the glow-up representation of a time distance between two points. i'm obsessed. ✨

🎀 NAME 🎀

std::chrono::duration< _Rep, _Period > — chrono::duration represents a distance between two points in time. no cap. 💅

🌸 SYNOPSIS 🌸

💜 Public Types

  • using period = typename _Period::type — this is the period type, the "tick" definition. it's giving "what's the unit, bestie?" energy. 🕰️
  • using rep = _Rep — the rep is the raw number type that holds the count. the main character of the arithmetic. 🔢

🦋 Public Member Functions

  • template<typename _Rep2 , typename = _Require< is_convertible<const _Rep2&, rep>, __or_<__is_float<rep>, __not_<__is_float<_Rep2>>>>> constexpr duration (const _Rep2 &__rep) — constructor from another rep. only works if the conversion is safe and you're not sneakily converting float to int. lowkey picky, highkey correct. 🙈
  • duration (const duration &)=default — default copy constructor. slay, it's free. 🫶
  • template<typename _Rep2 , typename _Period2 , typename = _Require< is_convertible<const _Rep2&, rep>, __or_<__is_float<rep>, __and_<__is_harmonic<_Period2>, __not_<__is_float<_Rep2>>>>>> constexpr duration (const duration< _Rep2, _Period2 > &__d) — constructor from a duration with a different rep and period. it's only allowed if the periods are harmonic and the rep conversion is chill. the vibe check is real. 🌀
  • constexpr rep count () const — returns the raw count. the number of ticks. the literal tea. ☕
  • template<typename _Rep2 = rep> constexpr __enable_if_t<!treat_as_floating_point< _Rep2 >::value, duration & > operator%= (const duration &__d) — modulo-assign by another duration. only if the rep isn't floating point. no floaties allowed here. 🚫🌊
  • template<typename _Rep2 = rep> constexpr __enable_if_t<!treat_as_floating_point< _Rep2 >::value, duration & > operator%= (const rep &__rhs) — modulo-assign by a raw rep. same deal, no floating points. 💀
  • constexpr duration & operator*= (const rep &__rhs) — multiply-assign by a raw rep. scale that duration, periodt. 📈
  • constexpr duration< typename common_type< rep >::type, period > operator+ () const — unary plus. returns a duration with the common type of rep. it's giving "i'm positive" energy. ➕
  • constexpr duration & operator++ () — prefix increment. add one tick. go off. 🔼
  • constexpr duration operator++ (int) — postfix increment. returns the old value, then adds one tick. classic. 🕐
  • constexpr duration & operator+= (const duration &__d) — add-assign another duration. stacking time. 🧱
  • constexpr duration< typename common_type< rep >::type, period > operator- () const — unary minus. returns the negated duration with common rep type. toxic negativity but make it chrono. ➖
  • constexpr duration & operator-- () — prefix decrement. subtract one tick. lessgo. 🔽
  • constexpr duration operator-- (int) — postfix decrement. returns old value, then subtracts one tick. the nostalgia. 🕑
  • constexpr duration & operator-= (const duration &__d) — subtract-assign another duration. time subtraction, bestie. 🧮
  • constexpr duration & operator/= (const rep &__rhs) — divide-assign by a raw rep. scaling down. 📉
  • duration & operator= (const duration &)=default — default copy assignment. iconic. 💖

🌈 Static Public Member Functions

  • static constexpr duration max () noexcept — returns the maximum duration. the biggest possible vibe. 👑
  • static constexpr duration min () noexcept — returns the minimum duration. the smallest possible vibe. 🐜
  • static constexpr duration zero () noexcept — returns zero duration. the void. the beginning. the end. 🕳️
note: these are not member symbols, bestie. they're free functions that live outside the class. don't @ me. 😌
  • template<typename _Rep1 , typename _Period1 , typename _Rep2 , typename _Period2 > constexpr common_type< duration< _Rep1, _Period1 >, duration< _Rep2, _Period2 > >::type operator+ (const duration< _Rep1, _Period1 > &__lhs, const duration< _Rep2, _Period2 > &__rhs) — adds two durations with different reps and periods. returns the common type. the friendship bracelet of chrono. 🤝
  • template<typename _Rep1 , typename _Period , typename _Rep2 > constexpr duration< __common_rep_t< _Rep1, _Rep2 >, _Period > operator* (const duration< _Rep1, _Period > &__d, const _Rep2 &__s) — multiplies a duration by a scalar. returns a duration with the common rep type and same period. math slay. ✖️
  • template<typename _Rep1 , typename _Period1 , typename _Rep2 , typename _Period2 > constexpr bool operator== (const duration< _Rep1, _Period1 > &__lhs, const duration< _Rep2, _Period2 > &__rhs) — equality comparison between two durations. returns bool. are they the same? iykyk. 🟰

🧚 Detailed Description 🧚

template<typename _Rep, typename _Period>
class std::chrono::duration< _Rep, _Period >

chrono::duration represents a distance between two points in time. that's it. that's the tweet. it's literally the measure of time between two moments, and it's giving main character energy. 💫

okay bestie, that's the whole page. this manual entry is from libstdc++ (the GNU C++ standard library), and it was auto-generated by Doxygen from the source code — so you know it's official. now go measure some time, periodt. 🕰️💖
