lossless_integral_conversion()

template<typename To , typename From , enable_if_t<(!std::is_same< From, To >::value &&std::numeric_limits< From >::is_signed==std::numeric_limits< To >::is_signed), int > = 0>

To fmt::v8::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.

template<typename To , typename From , enable_if_t<(!std::is_same< From, To >::value), int > = 0>

To fmt::v8::safe_duration_cast::safe_float_conversion	(	const From	from,
		int &	ec
	)

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