◆ as_bytes()

template<typename ElementType , std::size_t Extent>

span< const unsigned char,((Extent==dynamic_extent) ? dynamic_extent :sizeof(ElementType) *Extent)> gul17::as_bytes ( span< ElementType, Extent > s )

noexcept

Return a constant view to the byte representation of the elements of a given span.

This is a backport from the C++20 standard library, see: https://en.cppreference.com/w/cpp/container/span/as_bytes

Since: GUL version 1.9
