std::as_bytes, std::as_writable_bytes

template< class T, std::ptrdiff_t N>
std::span<const std::byte, S/* see below */> as_bytes(std::span<T, N> s) noexcept;

template< class T, std::ptrdiff_t N>
std::span<std::byte, S/* see below */> as_writable_bytes(std::span<T, N> s) noexcept;

Obtains a view to the object representation of the elements of the span s.

If N is std::dynamic_extent, the extent of the returned span S is also std::dynamic_extent; otherwise it is std::ptrdiff_t(sizeof(T)) * N.

as_writable_bytes only participates in overload resolution if std::is_const_v<T> is false.

Return value
