std::literals::chrono_literals(3cxx)

💖 NAME 💖

std::literals::chrono_literals — bestie, this is the 3cxx manual page for the ISO C++ 2014 namespace that hands you the cute little suffixes you slap on number literals to make chrono::duration values. No cap.

✨ SYNOPSIS ✨

okay so this namespace is just a big pile of overloaded operator'' friends, and here's literally every single one of them, no skipping 🫶

🎀 Functions

• template<char... _Digits> constexpr chrono::hours operator''h () — Literal suffix for durations of type std::chrono::hours
• constexpr chrono::duration< long double, ratio< 3600, 1 > > operator''h (long double __hours) — Literal suffix for durations representing non-integer hours.
• template<char... _Digits> constexpr chrono::minutes operator''min () — Literal suffix for durations of type std::chrono::minutes
• constexpr chrono::duration< long double, ratio< 60, 1 > > operator''min (long double __mins) — Literal suffix for durations representing non-integer minutes.
• template<char... _Digits> constexpr chrono::milliseconds operator''ms () — Literal suffix for durations of type std::chrono::milliseconds
• constexpr chrono::duration< long double, milli > operator''ms (long double __msecs) — Literal suffix for durations representing non-integer milliseconds.
• template<char... _Digits> constexpr chrono::nanoseconds operator''ns () — Literal suffix for durations of type std::chrono::nanoseconds
• constexpr chrono::duration< long double, nano > operator''ns (long double __nsecs) — Literal suffix for durations representing non-integer nanoseconds.
• template<char... _Digits> constexpr chrono::seconds operator''s () — Literal suffix for durations of type std::chrono::seconds
• constexpr chrono::duration< long double > operator''s (long double __secs) — Literal suffix for durations representing non-integer seconds.
• template<char... _Digits> constexpr chrono::microseconds operator''us () — Literal suffix for durations of type std::chrono::microseconds
• constexpr chrono::duration< long double, micro > operator''us (long double __usecs) — Literal suffix for durations representing non-integer microseconds.

🌸 Detailed Description 🌸

ISO C++ 2014 namespace for suffixes for duration literals. it's giving "time math but make it aesthetic" ⏰✨

These suffixes can be used to create chrono::duration values with tick periods of hours, minutes, seconds, milliseconds, microseconds or nanoseconds. For example, std::chrono::seconds(5) can be written as 5s after making the suffix visible in the current scope. The suffixes can be made visible by a using-directive or using-declaration such as:

• using namespace std::chrono_literals;
• using namespace std::literals;
• using namespace std::chrono;
• using namespace std;
• using std::chrono_literals::operator''s;

The result of these suffixes on an integer literal is one of the standard typedefs such as std::chrono::hours. The result on a floating-point literal is a duration type with the specified tick period and an unspecified floating-point representation, for example 1.5e2ms might be equivalent to chrono::duration<long double, chrono::milli>(1.5e2).

lowkey important: for the floating-point ones, the representation is unspecified — the page says "might be equivalent", so don't go writing code that hard-depends on it being exactly that type, bestie 😭
