add_sat()

template<class T >

auto detail::add_sat ( T  x, T  y  ) -> typename std::enable_if_t<std::is_integral<T>::value, T>

noexcept

Computes the saturating addition x + y for integral types.

Returns

x + y, if the result is representable as a value of type T. Otherwise, the largest or smallest value of type T, whichever is closer to the result.

bit_cast()

template<typename To , typename From >

auto detail::bit_cast ( const From &  src ) -> typename std::enable_if_t<sizeof(To) == sizeof(From) && std::is_trivially_copyable<To>::value && std::is_trivially_copyable<From>::value, To>

noexcept

Obtain a value of type To by reinterpreting the object representation of From.

This implementation is a polyfill for C++20's std::bit_cast.

Returns

A new object of type To with the same bit representation as src.
