lossless_integral_conversion()

template<typename To , typename From , FMT_ENABLE_IF(!std::is_same< From, To >::value && std::numeric_limits< From >::is_signed== std::numeric_limits< To >::is_signed) >

FMT_CONSTEXPR To safe_duration_cast::lossless_integral_conversion	(	const From	from,
		int &	ec
	)

converts From to To, without loss.

If the dynamic value of from can't be converted to To without loss, ec is set.

safe_duration_cast()

template<typename To , typename FromRep , typename FromPeriod , FMT_ENABLE_IF(std::is_integral< FromRep >::value) , FMT_ENABLE_IF(std::is_integral< typename To::rep >::value) >

To safe_duration_cast::safe_duration_cast	(	std::chrono::duration< FromRep, FromPeriod >	from,
		int &	ec
	)

safe duration cast between integral durations

safe duration_cast between floating point durations

safe_float_conversion()

template<typename To , typename From , FMT_ENABLE_IF(!std::is_same< From, To >::value) >

FMT_CONSTEXPR To safe_duration_cast::safe_float_conversion	(	const From	from,
		int &	ec
	)

converts From to To if possible, otherwise ec is set.
