◆ duration_cast_impl() [1/4]

template<typename ToDuration, typename ConversionFactor, typename CommonRep, typename Rep>
auto std::chrono::chrono_detail::duration_cast_impl ( Rep const & count,
std::false_type ,
std::false_type  ) -> ToDuration
constexprnoexcept

Helper for duration_cast implementation that handles different conversion cases.

Template Parameters
ToDurationThe target duration type
ConversionFactorThe conversion factor ratio
CommonRepThe common representation type used for the conversion
RepThe representation type of the source duration
Parameters
countThe current number of ticks
Returns
The new duration

Note: This handles the default case where ConversionFactor::num != 1 and ConversionFactor::den != 1 (section 2.4 of the C++ standard).

◆ duration_cast_impl() [2/4]

template<typename ToDuration, typename ConversionFactor, typename CommonRep, typename Rep>
auto std::chrono::chrono_detail::duration_cast_impl ( Rep const & count,
std::false_type ,
std::true_type  ) -> ToDuration
constexprnoexcept

Helper for duration_cast implementation that handles different conversion cases.

Template Parameters
ToDurationThe target duration type
ConversionFactorThe conversion factor ratio
CommonRepThe common representation type used for the conversion
RepThe representation type of the source duration
Parameters
countThe current number of ticks
Returns
The new duration

Note: This handles the case where ConversionFactor::num != 1 and ConversionFactor::den == 1 (section 2.2 of the C++ standard).

◆ duration_cast_impl() [3/4]

template<typename ToDuration, typename ConversionFactor, typename CommonRep, typename Rep>
auto std::chrono::chrono_detail::duration_cast_impl ( Rep const & count,
std::true_type ,
std::false_type  ) -> ToDuration
constexprnoexcept

Template Parameters
ToDurationThe target duration type
ConversionFactorThe conversion factor ratio
CommonRepThe common representation type used for the conversion
RepThe representation type of the source duration
Parameters
countThe current number of ticks
Returns
The new duration

Note: This handles the case where ConversionFactor::num == 1 and ConversionFactor::den != 1 (section 2.3 of the C++ standard).

◆ duration_cast_impl() [4/4]

template<typename ToDuration, typename ConversionFactor, typename CommonRep, typename Rep>
